/* Progress-Bar for Directory Opus 5.
by Leo 'Nudel' Davidson for Gods'Gift Utilities
email: leo.davidson@keble.oxford.ac.uk www: http://users.ox.ac.uk/~kebl0364
$VER: PBar.dopus5 1.4 (18.8.95)
This ARexx script will add a progress bar (like when deleting files)
to external commands which are run on all the selected entries in a
lister.
*** Could do with updating for Opus 5.5's new progress bars, although
it should work as is. If anyone is interested in an update let me know ***
Call as:
------------------------------------------------------------------------------
ARexx PBar.dopus5 {Qp} "<1>" "<2>"
------------------------------------------------------------------------------
Where <1> is the AmigaDOS command to be run for each file.
Insert "!!f!!" (without quotes) where you would like the full path to the
selected file (you can insert it more than once, if you require).
<2> is the progress window title.
If <1> or <2> have any spaces in them, "put quotes around them".
The "Do All Files" switch MUST be turned *_OFF_*!!!
e.g.
------------------------------------------------------------------------------
ARexx DOpus5:ARexx/PBar.dopus5 {Qp} "C:PackIt !!f!! CRUNCH" "Packing files:"
------------------------------------------------------------------------------
Note: The command you use must be able to handle "filenames with quotes".
TO DO:
------
- Convert this to a nice, fast assembler program - once I get to grips with
how to send Rexx messages via rexxsyslib.library (HELP!).
- Make it rescan all selected entries.
(Short of making it rescan the entire dir, which you can do as a switch
within DOpus, I don't think there is a way to emulate "Reload each file"
via an ARexx script, at least in the current version of DOpus5.)
- Perhaps propper support for all the {} type codes, not just {f}.
- ONLY DIRS and ONLY FILES options.
(If you don't want it to act on files or on dirs, simply don't select them!)
- Take a filetype-ID so that only files matching it are acted on.
(this would actually be a pain to impliment - I'm not about to).
v1.02 -> v1.03 - Now uses stem variables for getting the lister handle.
Some minor tidying up.
Now checks to make sure the DOPUS.x port exists.
v1.03 -> v1.4 - Now uses Show() instead of ShowList(). (Thanks Stoebi)
Style Guide compliant version numbering and $VER string.

/*- Function for Command-Line parsing -----------------------------------------
ARexx's "PARSE ARG" is rank. It isn't very good at handling arguments with
"quotes" (especially when the quotes are optional), and inserts spaces
where you don't want them sometimes. I don't have the docs to RexxDosSupport,
so I wrote my own function which extracts the next argument from the string
"CmdLine", respecting quotes, and not adding extra spaces at either side.
