Hi,
A long shot, as I'm using IDL 5.4 under OpenVMS 7.1.

Is there a way of running a sub-process (perhaps using SPAWN) and capture
its output as it happens to a text widget. I am aware I could use the RESULT
keyword, but that is only available when the SPAWNed process completes.

It may be possible to use a CALL_EXTERNAL using mailboxes to communicate,
but this seems a bit heavy handed.

I can always supply more info if required.

Regards,
Ian
