Mike, if I understand you correctly...
If I have an IDL app that I want to be able to pass parameters to from
the command line, I:

1) write my parameters that i wanna pass to a params.txt file, 1
parameter per line. e.g, if my code takes 2 parameters, params.txt
will read:
./indata/file1.hdf
./outdata/outfile1.hdf
For what you want, passing from a command shell I think, this params
file is written to with a command script.

2) I write a wrapper routine (e.g. wrapper.pro) who's job is to read
in the params file then call my app with the appropriate params.

3) Open IDL with this wrapper.pro, compile it, resolve_all, save,
/routines, filename='whatever.sav'

Now, I can run from a command shell. Run the script that that'll write
your params to params.txt. In the script call idl runtime. On unix,
idl -rt=whatever.sav. On win, idlrt whatever.sav

Of course, if your parameters never change, or you just wanna change
them yourself with a text editor, you don't need to bother writing a
shell script. I keep mine general b/c many times i'm processing files
automatically at a certain time of day and i use a script to query an
input dir to see when new files arrive (script grabs by ftp) for
processing. When a new file arrives, regardless of it's name, the code
runs automagically.

Hope this helps,
todd
