Hello Tristan,
I need to look into my stuff, but that won't happen before next week. If I understand you correctly, you want to "shut down the output of the task, no matter what." I think, I have done this somewhere ... but I do not remember the details. You need to place " ' drop " in the correct field in the task control block. Something like this ... I'll check this out next week. :-) Cheers, Erich Tristan Williams writes: > Hello, > > I have been trying to redirect emit from within a task in a forth > multitasking setup.
