Mach -  Mouse Accelerator with Hotkey.           Version 1.4  12-23-87.
MachClk - Mach + Title Bar Clock and Beeper.     Version 1.0  12-23-87.



    NOTES: 1. Mach is identical to MachClk minus the clock. Features that
              apply only to MachClk are so noted.

           2. References in this document to "Qualifier" means either the
              left or right Alternate or Amiga keys depending on whether
              or not you use "-a" on the command line.

           3. When used on the command line, function keys are single digits.
              1 is F1, 2 is F2, 9 is F9, and 0 is F10.

    USAGE:

       Run Mach [nscmdaeb] hotkeystring hotkeystring...hotkeystring
                            or
       Run Mach [nscmdaeb] +1hotkeystring +2hotkeystring...+nhotkeystring

                            or

       Run MachClk [nscmdaebkt] hotkeystring hotkeystring...hotkeystring
                            or
       Run MachClk [nscmdaebkt] +1hotkeystring +2hotkeystring...+nhotkeystring


     Arguments: All optional. Any order.

     -n    Acceleration factor where n >= 0 && n <=9.
     -s    Removes sunmouse.
     -c    Removes click to front.
     -m    Removes the trapping of left-amiga-m. (allows normal use)
     -d    Adds double control feature.
     -a    Use the Amiga keys as qualifiers.
     -estr Use str as execute string. Default is "NewCLI >nil: <nil:".
     -bnn  Time delay before blanking screen. 0-99 minutes. 0 = no blank.
     -knnn Put Clock left edge at nnn. (MachClk only)
     -tnn  Beep every nn minutes. Default 15. (MachClk only)


    Hotkeys:

       The hotkeys are the keys F1 to F10 qualified with the left or
       right alternate keys. If you prefer to use left or right Amiga, put
       -a on the command line. This makes it more compatible with WordPerfect
       and other programs that make use of alternate-function keys.
       The escape character "\" may be used to introduce newline or a function
       key or to add qualifiers.
         \n  newline
         \c  control
         \a  alternate
         \A  Amiga
         \s  shift
         \f  function key where f is 1-0 = F1-F10

         c, a, A, s modifiy the next letter. They can be combined.
         c, s, and n may be upper case.
         Examples:
              \C\a\3  sends Control-Alternate-F3.
              \A\0    sends Amiga-F10.

         Hotkeys may call other hotkeys.

       The hotkeys are defined in the command line following the optional
       options. Definitions with embedded spaces should use "".
       They may be positional, that is, the first definition is matched
       with F1 and the second with F2. Or, you may specify a function key
       with +n. n = 1 - 0. 0 is F10. No spaces may follow the key number.
       e.g. Run Mach "+5diskcopy df0: to df1:\n"
       See more examples below.
       You may redefine hotkeys by running Mach again with new definitions.
       e.g. Mach +3dir\n "+0run df1:wp\n"

    Accelerator:

       The accelerator speeds up mouse movements. It accepts as an argument
       a number, 0-9, which sets its speed.
       -1 is the default, -0 = no acceleration. (I use -4).

    NewCLI:

       The qualifier and ESCape combination will create a NewCLI.
       You need to have NewCLI and Run in the c: directory. You can change
       this from NewCLI to another command with -estring. A full window
       can be used with "-eNewCLI CON:0/0/640/200/MyCLI".
       The NewCLI will have the same size stack as Mach.

    Screen Blanker:

       After 5 minutes of no mouse or keyboard activity, the screen will
       go blank. You can change this default with -bnn where nn = 0 - 99
       minutes. 0 disables blanking.
       Instant blanking: Control-Qualifier-F2.

    Sun Mouse:

       The window that the pointer is over becomes the active window
       after the first mouse movement. To be able to drag icons, the
       sun mouse is disabled while the left button is held down.
       If you don't want the sun mouse, use -s on the command line.
       On/off toggle: Control-Qualifier-F3.

    Click To Front:

       You can click in any part of a window and bring it to the front.
       If you don't want this, use -c on the command line.
       On/off toggle: Control-Qualifier-F4.

    Screen Shuffler:

       Left-Amiga-M will push the front screen to the back instead of
       pushing workbench screen to the back.
       Left-Amiga-N will still bring the workbench to the front.
       This is useful if you have more than two screens on at once,
       especially if they don't have screen depth gadgets.
       If you don't want this feature, use -m on your command line.
       On/off toggle: Control-Qualifier-F5.

    Clock:

       MachClk has a title bar clock that displays available memory and the
       time. You can change its left edge position with -knnn. For no clock
       use -k0 or -k. The clock is updated every second and brings itself
       to the front (if covered up) every 4 seconds except when the left
       button is held down. The current toggles are shown in the left corner.
       They are s: sun mouse, c: click to front, m: Amiga-M screen shuffler,
       d: double control, a: Alternate/Amiga qualifiers.
       On/off toggle: Control-Qualifier-F8.

    Beeper:

       MachClk (when the clock is activated) has a beeper (to keep you awake)
       which defaults to a 15 minute interval. Change this with -tnn.
       nn = 0 to 60 minutes.

    Uninstall:

       Use the combination Control-Qualifier-F1 to uninstall Mach or MachClk.

    Toggles:

       These key combinations can be used to toggle specific features.

        Ctl-Qualifier-
          F3  Sun mouse.
          F4  Click to front.
          F5  Screen shuffle.
          F6  Double control.
          F7  Alternate/Amiga qualifiers.
          F8  Clock. (MachClk only)

        F3-F7 are displayed in the clock as [scmda].

    Instant blanker:

          Ctl-Qualifier-F2  Causes the screen to go blank immediately.



    EXAMPLES:

       Run Mach -2 -m -s df0: df1: "dir\n" "copy " "" "run sys:system/rollodex"
         This maps
             Alternate-F1 to  df0:
             Alternate-F2 to  df1:
             Alternate-F3 to  dir + return
             Alternate-F4 to  copy
             Alternate-F5 to  nothing
             Alternate-F6 to  run sys:system/rollodex

         The options set the acceleration factor to 2, allows the normal use
         of Left-Amiga-M, and disables the sun mouse feature.


       Run MachClk -a -0 -c -b12 "run df1:wp\n" +5df0: \s\c\1 \c\A\0 dir\n\A\1
         This maps
           Amiga-F1 to  run df1:wp + return
           Amiga-F5 to  df0:
           Amiga-F6 to  Shift-Control-F1
           Amiga-F7 to  Control-Amiga-F10
           Amiga-F8 to  dir + return + Amiga-F1

         The options set the acceleration factor to 0, the function key
         qualifiers to the Amiga keys, disables the click to front feature,
         and sets the waiting before blanking to 12 minutes.
         The clock is placed in its default position and the beeper interval
         is the default 15 minutes.


       Run MachClk -k200 -t30 -4 -a "diskcopy df0: to df1:\n"
         This maps
           Amiga-F1 to  diskcopy df0: to df1: + return

         The options use 200 for the clock's left edge, sets the beeper
         interval to 30 minutes, the acceleration factor to 4, and the
         qualifiers to the Amiga keys.



    REDEFINING:

       Mach may be run again to redefine hotkeys or set the blanking
       time delay or the beep interval or to change the toggles.
       For example, after Mach is running, typing "Mach -6 +5df0:"
       will change the acceleration factor to 6 and redefine F5 to "df0:".
       Only the clock position may not be changed this way.

       Mach -b10 +3CCC +2BBB +5EEE FFF
         This redefines
           Qualifier-F2 to  BBB
           Qualifier-F3 to  CCC
           Qualifier-F5 to  EEE
           Qualifier-F6 to  FFF

         and resets the blanking delay to 10 minutes.


       Mach -eWack
         This changes the Qualifier-ESCape command from NewCLI to Wack.
         Remember, the executed command will have the same size stack
         as Mach.


    MISCELLANEOUS:

       Note that anything after a semicolon is treated as a comment.
       If you are typing this in from the CLI, when you reach the end of
       the line, don't hit return and you can continue mapping up to 255
       characters (including run mach [options]). If you are using an editor
       or word processor, use one that can handle long lines. You can use
       Ed but you need to use the command SR or EX. You can then put this
       in your startup-sequence.

       I have found that the hotkeys do not function properly with the
       program Sili(Con:).
       Let me know if you find other incompatibilities.

       If you do "stack 2000" before you run Mach, it will use about
       16k. Be sure to reset your stack to 4000 or higher after this.
       MachClk uses about 4k more than Mach.
       If for any reason Mach fails to run (e.g. no free signals, no
       input.device??) it will use a return code of 10 or higher.

       The NewCLI brought up by Qualifier-ESC will have a stack the same
       size as Mach. Many programs that you may run from this CLI need a
       larger stack so either run Mach with a larger stack or, after you
       get a NewCLI, use the stack command to set your stack to a larger
       value. If programs mysteriously crash when run from the NewCLI, it
       may be caused by the stack size.

    Hidden Control Feature:

       If you happen to be a one handed typist, you know what a pain
       it is when you need to do a Control-F10 or any combination of
       the Control key and a key on the right side of the keyboard.
       If you put -d on the command line, you can still use the Control
       key in the normal way but if you hit it twice in a row, the NEXT
       key will have the Control qualifier added to it. This excludes
       the shift, alternate or amiga keys so, for example, ctl-ctl-f10
       is the same as ctl-f10 but you don't need to hold down the control
       key. Ctl-ctl-shift-p is the same as ctl-shift-p.
       Note that this is normally disabled unlike all the other features.
       On/off toggle: Control-Qualifier-F6.

FixBoot 0.0, Copyrighe © 1987 by Jerry Masker, Getzville, N. Y.

This program may be copied and used freely as long as the original copyright
notice in the program is left intact.  The author makes no warranties of any
kind about this program - USE AT YOUR OWN RISK!

Certain early programs for the Amiga were not designed with expanded memory
in mind.  Some of them auto-boot as a workbench disk, thereby precluding the
use of the NoFastMem program supplied with the Amiga 2000.  This program has
been implemented to solve that problem.  Some of the programs this program
effectively fixes include Arcticfox and Skyfox.  It will also work with
Deluxe Print, although the NoFastMem program could be placed on the disk
and executed manually.

This program reads in the bootblock of the requested disk.  It then copies
the existing program boot code down in the bootblock and inserts a small
segment of code which, upon booting the disk, eats all the available
expansion memory.  A new blotblock checksum is calculated and stored in the
bootblock, and the bootblock is written back to disk.

To use this program, setup using the following CLI commands:

   copy FixBoot ram:
   cd ram:

Then, REMOVE ALL DISKS FROM THE SYSTEM in case you make a mistake.  Insert
the disk to be repaired, with write enabled, in any of the drives and type:

   FixBoot <drive number>

Notes:

   1. Use a COPY of the disk to be fixed in case something goes wrong! You
      may have to use one of the copy programs such as Marauder if the
      original is copy protected.

   2. Error reporting by this program is almost nonexistent.  For example,
      if you forget to write enable the disk, the program probably will not
      report it.

   3. The program assumes that there is space available in the bootblock for
      the "memory gobbler" to be inserted.  I have not seen any programs
      where the bootblock contained so much code that this segment could
      not be inserted.  HOWEVER - if you execute this program several times,
      on the same disk, you will be inserting multiple copies of the "memory
      gobbler", and will eventually overflow the bootblock.  Extra "memory
      gobbler" segments typically won't hurt anything unless this condition
      arises; but the old saying "if a little's good, a lot must be better"
      certainly doesn't apply here!

   4. The VIP PROFESSIONAL spreadsheet program disk does not have a problem
      with extra memory; you must use it in drive df0: on the A2000.  Its
      problem is that there isn't a drive df1: on some machines, and the
      code searching for drives leaves a lot to be desired.  Anyway,
      FixBoot won't help - it only hurts by reducing the size of the
      spreadsheets the program can handle.  (Also, with VIP, don't forget
      to change stack to 40000 if you have extra memory installed.)

   5. See also my program HackerFix to repair Hacker I disks.  FixBoot
      is not needed for Hacker I.

Virus-Checker.Doc

This program can check for the presence of either of the two currently
known Amiga viruses.  It can check for the presence in memory and
optionally on a specified disk drive.

  If found in memory, it will clear out the offending virus.  If the virus
is discovered on a disk, you may use the DOS command INSTALL write a new
boot track and clear the disk of the virus.

   CAUTION -- using the INSTALL command on some commercial (game) disks
may destroy the copy protection and render the disk unusable.

WBDepth (c) Copyright 1987 by Andry Rachmat


	Have you read the info on how to modify KickStart disk so that
you can have 8 colors on the Workbench? Interesting, isn't it?

	The unfortunate things are you, 500 & 2000 & kickstart on the rom
owners, are left in the cold, and it is a hassle if you want to change
the depth back and forward (i.e. you need to reboot with different
kickstart disk everytime).

	Well, here comes 'WBDepth' to the rescue....
What WBDepth does is simply changes the number of planes of the WB screen
on the fly. No need to reboot, no need to bother with kickstart disk.

Usage:
	WBDepth [number]
Example:
	WBDepth		-> will show the current WB screen parameters
	WBDepth ?	-> will show the usage
	WBDepth 1	-> change to 1 planes (2 colors)
	WBDepth 2	-> change to 2 planes (4 colors), standard
	WBDepth	3	-> change to 3 planes (8 colors)
	WBDepth 4	-> don't try it, unless you are ready to reboot

	This is CLI only program, [number] is a single digit number 1-5.
However, don't use number greater than 3. The ability to use the number
greater than 3 is just there to show that the system will screw up,
and will hang, and perhaps will guru (CATS: what is wrong here ?).
If you want speed use 1, and if you want fanciness use 3 (8 colors).

	To see the speed variation, here some timing for 'Type'ing a
4000 bytes text file on CLI (Blitzfonts installed).
	3 planes: 15   seconds
	2 planes:  9   seconds
	1 plane :  5.5 seconds
(note: no wonder if 'Blitz' can go that fast, being written is assembly
plus only using 1 plane for sure will help the speedup).

	8 colors will be suitable for self-bootable graphics demo disk.
In that case you might need to grab 'SetColor' on the 'WBench8.arc'
(this arc file contains the infomation on how to modify the kickstart
disk to get 8 colors, and some utility programs). Setcolor will allow
you the change the extra 4 colors (color 4-7) automatically. For
manual changes you can use 'PopColor' or 'ColorDemo'.

	All programs mention here are PD or Shareware, and so does this
program. It is a Public Domain, dedicated to ALL PD and SHAREWARE authors.
Thanks for writing GREAT programs for this GREAT machine that we all LOVE.
	Also thanks to Sysops across the nation for keeping PD programs
distributed. I know it is a dirty job, but somebody got to do it.

	Finally to you all, AMIGA users, Merry Christmas!!!

- Give a big favor will you, spread this program around. Danke!

What is ScrinkWrap?  ScrinkWrap is a program which allows you to resize any
WINDOW (not screen) regardless of its status, size etc.  As long as you know
the windows name, it may be resized!

After receiving FACCI (great program Perry! FACCIIs even better) I did'nt
like having the window around (read noticible) all the time.  So I thought
it would be nice to just resize it so small it would be less noticable.  Well
I was just learning "C" at the time and was very busy so the project was
canned (anyway AUTOFACC did a nice job ;-) ).  Recently I had a similar pro-
blem come up where I wanted to get rid of a window with no sizing gadget, hence
ScrinkWrap.  Originally ScrinkWrap just scrunk AmigaDOSs window down to 1X1
just like a similar program called Tiny.  I thought it would be fun to resize
any window (not a very nice thing to do but fun anyway), so ScrinkWrap grew
to where it is today.

Great so how do I use it.  I'm glad you asked.  ScrinkWrap is pretty easy to
use, the following is a brief rundown of its syntax:

ScrinkWrap                          - Will look for the window named 'AmigaDOS'
                                      and scrink it to 1X1.  Great for Work-
                                      bench users who want a CLI around!  To 
                                      use it just click in the upper left-hand
                                      corner of the screen, and then type your
                                      command.  You may also go to the upper
                                      left corner and drag the window open 
                                      again!

ScrinkWrap <anyletter>              - This will run thorough the list of active
                                      windows and write them to the screen, 
                                      providing the letter you use is not a 
                                      current window title.

ScrinkWrap New                      - Will look for the window titled 'New'
                                      (note upper/lower case) and scrink it
                                      to 1X1 pixels.

PLEASE READ!!

Known problems/side-effects.  Since some windows were not designed to be 1X1
pixels.  DOS sometimes has problems redrawing the title bar and left border.
If this occurs, just resize the window and hopefully DOS will redraw.  
Normally the upper 1/4 of the left-border will disappear.  This will not 
affect the operation of the window it is just a little annoying.  ScrinkWrap
does NOT mess with MinWidth/Height of windows, so if a window has been scrunk
and you attempt to resize it, it will only scrink back to its minimum dimen-
tions.  If you forget and use the 'a' autosize function on a Workbench window,
you will get a Guru (use the 'A' function for Workbench windows).  ScrinkWrap
does not work correctly under Shell 207, make sure (if you are a Shell user)
to start a New CLI before using ScrinkWrap.  Or if it is in your startup-
sequence, make sure it is before your call to Shell.  ScrinkWrap was designed
for experimentation.  Please have fun with it, it was a two day hack so it 
probably has a few bugs.  I use an A1000 w/2 drives and a 2 meg StarboardII.
I have not tried it on any other system but my own so I would appreciate 
hearing your bug reports/comments etc!

Please send any feedback/comments to:

                             DropCloth
                            Version 2.2
                          By Eric Lavitsky

DropCloth lets you place a pattern, a 2 bitplane IFF image or a
combination of a pattern and image into your Amiga's WorkBench
backdrop.

To use DropCloth from the CLI, type:

		1>dropcloth [-d number] [-i filename]

where "number" is between 0 and 64 inclusive and "filename" is a
valid 2 bitplane (4 color) IFF image file. The number specifies
the intensity of the pattern used for the backdrop, 0 will render
a clear pattern	into the display, while	64 will render a solid
backdrop. If you don't specify a pattern, DropCloth will default
to 0, a clear pattern. To remove DropCloth and any pattern or image
it has rendered into the backdrop, simply run DropCloth a second
time. It is generally recommended that DropCloth be "RUN" or
"RUNBACKED" from the CLI.

To use DropCloth from the WorkBench:

		Double click directly on the DropCloth Icon or
		Double click on an IFF image Icon whose default
		tool points to DropCloth.

The image must be an IFF image (ILBM). Change it's default tool to
point to DropCloth. Assuming DropCloth resides in the C: directory,
select the image icon and then select "Info" from the WorkBench menu.
The next to last field in the Icon is the default tool:
			      ____________________________
		DEFAULT TOOL  | C:DropCloth              |
			      ----------------------------

If your image does not have an Icon, you may create an Icon for it by
copying one of the Icons normally created by DPaint. If you want 
DropCloth to render a pattern, specify the pattern you want in the
ToolTypes of the DropCloth Icon (if you are rendering a pattern only)
or in the ToolTypes of the image Icon (if you are rendering an image
along with a pattern). Again, select the Icon in question, pull down
"Info" from the WorkBench menu, go down to the ToolTypes field, select
"ADD", click in the ToolTypes text gadget and enter:
		_________________________________
		|PATTERN=n			|
		---------------------------------

where n is again a number between 0 and 64 inclusive.
To remove dropcloth and any pattern or image it has rendered into the
WorkBench backdrop, simply run DropCloth a second time by double
clicking on it's Icon.

- Features and Limitations
	- Current version wants 640x200x2 images - patterns work fine in any
	size screen including "morerowed" (overscan) screens.
	- We make a few assumptions about the IFF image that limit us to
	accepting only 2 bitplane images.
	- The fuel gauge in main disk windows is not properly refreshed by
	RefreshWindowFrame() ... (sigh)
	- Requires V1.2 or greater of KickStart to run

- Future considerations
	- We could give an option to add bitplanes to the workbench screen for
	images > 2 bitplanes or try and map colors to 2 bitplanes. This would
	slow things down and eat lots of CHIP memory (ugh!).

HISTORY

- How it started
	- When I first got my Amiga way back in August '85, I was
dissapointed to find that I couldn't put an image or pattern in my
backdrop like we could on the AI workstations and Macintoshes at Rutgers.
	- One day, someone posted on the net that at a gathering in the
Apple Computer cafeteria one day, Andy Hertzfeld, of Macintosh design
team fame, was quoted as saying that the Amiga wasn't a serious machine:
"C'mon,	a user interface with windows the same color as the screen?!!!".
I vowed that one day, I'd show him! :-)
	- One day, in one of our usual hacking sessions, Perry Kivolowitz
and I started fooling with the layers library to see what we could make it
do.  It was here we discovered that the WorkBench backdrop was a backdrop
borderless window and that we could look at it as a layer.
	- On Sunday February 8th, 1987, Perry and I decided to take a trip
over to Rutgers (just 10 minutes away) to take a look at how the Suns and 
Macintoshes allowed you to change backdrop patterns and images.
	- That same night we went to his apartment to begin writing our
own backdrop enhancer for the Amiga. At	eight o'clock the next morning we
had DropCloth in what essentially became release 1.0 (it was heavily
cleaned up first :-)
	- We had hoped that DropCloth would be part of a complete package
of tools and enhancments for the Amiga,	but soon decided that it couldn't
be supported well since it could degrade the preformance of the workbench
(notice the delay incurred from clicking a disk icon to it's being available
to be dragged). So, the project was shelved in favor of other things.
	- Suddenly, we saw other people on Usenet attempting the very same
thing (doesn't it always happen this way, Amiga hackers are always on the
same wavelength). We posted the V1.0 binary so people could have patterns
at last. The V1.0 release was also placed on Fish Disk 59
	- About two weeks before the first AmiExpo in New York,	Perry and 
I were talking about DropCloth again. He asked me if we really couldn't
put an image into the backdrop (at one point we thought we couldn't for
some silly reason). A large rock promptly hit me in the back of the head
and voila! (Get the source to see how it's done).
	- Perry's wrote the initial code for rendering more than just a 
pattern into the backdrop for a nice little demo at AmiExpo. I took his
prototype and extended it to allow all IFF images and put in WorkBench
support as well.

- What it does
	- Things we had to realize about the workbench:
		- The Workbench renders it's icons into a 
		backdrop borderless window.
		- When an icon is moved SetRast() is called to
		clear the layer and all the icons are redrawn.
		This is fairly fast, but destroys anything you
		render yourself into the backdrop.
	- So, get the source to see how it's done! (plug, plug :-)
