I was just digging through some old emails and evidently I saw this
problem before but forgot about it (I hardly use IDL). I guess the
Windows implementation of IDL VM is slightly f-ed up. Not a huge
deal but annoying and I wish it was better documented (better still
if they actually got it to work).

This is a bit of a bugger, isn't it?

My workaround is RHTvmConsole, a simple widget replacement for the PRINT
and READ procedures. You can drop it in with a simple find/replace and
it should handle the basics.

I guess the problem is that in the VM you don't have access to stdin
(command line) and stdout (output log).

I sometimes use

IF ~lmgr(/runtime) THEN ...

to include code which should be executed only in a fully licensed IDL
environment.
