I am pretty sure that you can't do this on win32. IDL for windows can't do
I/O with the command prompt. That program that ran briefly was the runtime
engine and the output of your 'hello world' program went straight to
/dev/null.

Although I haven't tried it, I suspect that Craig's suggestion will still
route I/O to IDLDE so that's no good for you. And you would still have a
problem with I/O on the runtime licensed machines.

I think your only option is either have everyone telnet to a UNIX box
running IDL or build a GUI. You could easily build a simple IDL based
"terminal" that could accept text input and print output.

But before you do that, email RSI and add your name to the list of people
who want a command line version of IDL for windows. We have to make up over
50% of the machines IDL is running on. We demand parity! :o
