[Tutor] Popen and Prompting

[Faulconer, Steven M.]

John,

I thought about that, but it would potentially cause other conflicts. I
think our final plan is to edit the code to die on error cases instead of
prompting. However, if anyone knows of a way of handling this, I'd love to
know for future use. Thanks for the response.

Steven

Could you kludge it?

eg, change the C programs so that, every time they ask for user input,
they include in the prompt a certain unusual string.  Then, any time
your GUI detects this string in the program output, it can pop up a
dialog box asking for user input.

(just a suggestion ... I don't know the best way of dealing with this)
