[Coco] OS9 Programming question

[Bill Pierce]

What sort of flags? The forked processes already have the keys in question intercepted. They still seem to go to the buffer. This occurs no matter if the forked process is in C or ML. I think the real problem is that the forked processes are running in the same window path therefore sharing the same stdin & stdout.


hi

maybe you can set flags for each window, and clear all the flag on return
to the main code. This would avoid having pending breaks. ofcourse the
polling of all the flags needs to be done on entry in the main code.

i hope this gives you ideas.
