MultiLHA1.rexx and MultiLHA2.rexx are the result of a recurrent need: to
archive a bunch of files from different disks or directories to a single
file. While waiting for all this to be accomplished, DOpus will be "busy"
and not available for other uses. Hence, the MultiLHA scripts were called
into being. They will allow you to select a bunch of files from a variety of
disks or directories, then quietly multi-task in the background while they
perform the actual archiving.

They work in 2 parts, building the filename list, and then in the second
program, processing that list and archiving the files.

I have the two scripts assigned to the same button gadget, selectable with
both right and left mouse buttons:

Edit your startup-sequence to read   Assign >NIL: Rexx: S:
(if you have not changed your original Startup (WB 2.x / WB 3.x)  you will not have to do this.)
next copy the *.rexx and the .boot files to your S: then load DOPUS

First Load Config For Opus Find A Spare Button And Do The Following:-

Left button -  Name: MultiLHA, Function:  Rexx  Path:  REXX:MULTILHA1.Rexx,
Flags:  run async,
Right button - Name: Create  , Function:  Rexx  Path:  REXX:MULTILHA2.Rexx,
Flags:  CD Destination / run async. 

MAKE SURE YOU ARE RUNNING REXXMAST 

MultiLHA1.dopus builds the filename list, and you can keep selecting files
from different disks and directories until you get all that you want. You
don't have to worry about taking files from multiple floppies, the script
will ask for them back again when it needs them.

Once you have selected all the files you want, you can call the second
script to actually perform the archiving function. The output file will be
created in the currently selected directory, and you will be prompted for
the filename.

Note that while the scripts will handle recursive directories, the number of
files within those directories are not counted, I just use the * option to
grab them all. If you want an accurate count, enter the directories and
select all the files within it, not just the directory itself.

Note that the filelist is built up in a file called RAM:infiles.txt, and
then after it is all processed, that temporary text file is erased. Also,
the program LHARC is used to perform the archiving, and it is copied into
RAM: before the archiving begins. If you're low on ram, this might cause a
problem. Once the script is finished, RAM: is cleaned up again.

If you need to abort the file selecting process and totally start over, you
must manually delete the file RAM:infiles.txt, or your new list will be
added to the original list. This file is automatically deleted when the
scripts complete, you only have to delete it yourself if you want to abort
before it is finished.

While you may not have a particular need for this type of use, the scripts
make good examples of how to snatch filenames from DOpus into your own AREXX
scripts for whatever you want, as well as how to send messages back to
DOpus for user display.
