I'm a novice in IDL, so please bear with me. I want a procedure to
display a prompt with a text field. From what I understand,
promptusertext is the method I should use. This said, I can't get it
to work properly. The prompt never displays and just registers the
user's entry as 0. Here's my code:
PRO ...
...
obj = Obj_New("IDLitIMessaging")
result = obj->promptusertext('...', answer, title='...')
...
END
What am I doing wrong?

I wish they would just get rid of that *%@ run button!!
I hate to tell you this, but that good-for-nothing run
button only runs main-level programs and procedures that
take no arguments. That is to say, an *extremely*
small fraction of the IDL programs you plan to use. :-(
Try going to the IDL command line and typing this:
IDL> answer = TextBox()
Cheers,
David

Yes, I saved it in my hard drive, compiled and hit the run button. Is
there any specific command to run it?
Thanks!

What command did you type to run it?
Did you put the file somewhere on your IDL path?
Cheers,
