Have you considered placing a wrapper around their program?

Subject: Re: [U2] Sending interrupt to UniBasic program
Thanks to the suggestions from various posters, I have determined that my
incriminations of screen were malicious libel. It's not screen. The issue
of not being able to send an interrupt (e.g. kill -2/SIGINT) is a result
of how I had to work around something in the third-party code I'm trying
to automate.
There are a couple input prompts, e.g. "do you want to continue? y/n" that
I originally tried to handle with DATA statements. But the 3rd party
software is doing something to clear the input stack. I've tried a few
different workarounds, including hacking the CLEARINPUT verb, with no
success. I finally got it work by doing a PCPERFORM as follows:
PCPERFORM 'echo PROGNAME\\nY\\n\\n\\n | udt'
This works great except that a SIGINT issued to the newly spawned udt
process has not effect. A straight kill works, but it actually kills the
udt process which is precisely what I do *not* want to happen.
Any creative thoughts on how to get a SIGINT to work? Maybe a different
way of calling PROGNAME? Talking to the vendor about changing their code
is a theoretical option, but involves $ and a good deal of time, so is not
preferred.
TIA,
Brad.
