Sorry to quibble Michael, but what you're referring to, I think, is
IDL's lack of a *console-mode* executable on Windows (and I did mention
this lack, in connection with IDLWAVE integration). I have submitted a
feature request for such a beast--after threatening to do so many times
on this group. I haven't got a response yet and I doubt it is a high
priority. If a few more people add their $0.02, perhaps the priority
will rise a little. To see proof that an IDL console-mode executable
would be feasible, just look at Python.
IDLDE on Windows can be launched from a command line and it does accept
command-line parameters. (Like IDL on other platforms, the command-line
capability was enhanced substantially in version 6.2 to support
automated operation.) However it is not a console-mode program so it
always opens a GUI and it cannot interact with the calling process via
stdin and stdout. So you are quite right to say that it doesn't play
very well with shell scripts, WWW-page processing and remote logons.
And by the way, people, please don't refer to the Windows console-mode
command-line and batch-file processor, cmd.exe as a "DOS prompt". OK,
Microsoft have been known refer to it in this way, but it has nothing to
do with DOS.
