M e g a D O S      v1.3
                            =========================

In Megabase, there was a quite attractive CLI system, called MegaDOS.  Pity
was, Megabase itself was crap.  So, I have ripped it from Megabase. 
Re-Paletted the colours, spoofed it up, improved commands and routines, and
so this is v1.3

The difference between AmigaDOS and MegaDOS
-------------------------------------------
Although both completely different, they have many similarities.  But,
there are 2 main problems with MegaDOS...

 1. All COMMANDS must be in lower case.
 2. Any name of value, must be enclosed in speech marks.

These are the only problems.  

There are MANY similar commands, such as DIR, RENAME, MAKEDIR, CD, COPY,
and there are many EXTRA ones, like, MOVE, LOAD, PLAY, START MUSIC, STOP
MUSIC, CLEAR MUSIC, INFO......

Commands
--------

The LOAD command, loads up either a sample bank or music bank.  Samples can
be played, using the Play command like this...

           Play "number" "frequency"

Or Music, can simply be played with a START MUSIC command.

Here is a quick list.  

                  dir "path and/or filter"
               rename "source" "destination"
              makedir "new-directory"
                   cd "new-directory"
                 copy "Source file" "Dest Path+DEST NAME"
                 move "Source file" "Dest Path+DEST NAME"
                 load "filename"
                 play "number" "frequency"
                start ( Starts any music in the Bank ) 
                 stop ( Stops any music playing )
          clear music ( Clears the Music Bank. ( 3 ) )
         clear sounds ( Clears Sample Bank ) 
               prompt "new prompt"
                   ed "filename for new BATCH file"
              execute "MegaDOS batchfile name"
                 view "IFF Picture name ( Click to Exit )"
               system ( Displays CHIP, FAST and TOTAL )
             listbank ( Displays any banks currently in memory )
                 amos "-filename- to run "                

MegaDOS is best compiled.  During creation of this disk, MegaDOS was used
to clean up files, sorting out directories, installing things, e.t.c.
The good advantage, is that no commands have to be on a certain disk, they
are all memory resident.  Unlike DOS of course.
Being written in AMOS though, causes problems for people to add new
commands of their own.  But, it is not too much of a problem, just read the
TECH section of this document, to see how AMOS programmers can add their
own commands.


Tech

How to add commands:

All command data is held in the procedure, ANALYZE. 

It is quite simple.  Firstly, your programming will go something along the
lines of....

 If left$(c$,length of command)="command"
    . . .
    Actions
    . . .
    Goto EN           ( This must be last, and it MUST be included )
 End If

You can call 2 procedures.  GTWORD, and GT2WORD.  The first one, gets
anything following the command, and puts it in the string F$. Useful for
commands like the PROMPT command.  GT2WORD, gets 2, and the second is put
in the string, F2$.  Useful for commands like RENAME, and COPY.

Here is the general idea.... ( For the PROMPT command )

 If Left$(C$,6)="prompt"            ( Notice, the LOWER CASE )
    GTWORD                          ( Gets the string held in "" )
    P$=F$                           ( Prompt string held in P$ )
    Goto EN                         ( Goes to the label EN, at the
                                      end of the Analyze procedure )
 End If                             ( Ditto ! )

 This means that if the user types `prompt "MegaDOS >"', then the following
things happen....

    GTWORD......

            - Finds "", gets the middle bit, `MegaDOS >'.

    P$=F$
            - Makes P$ equal the characters which were types

    Goto EN - Goes to the end of the procedure

 Then on the next input...

 MegaDOS >

 Easy huh ?!
