BTW, how does one cite the contents of a message one is responing to in this forum?
First off: I'm not about to rewrite the C program in Swift. That's absolutely outside of any consideraton in this case.
a) complexity
b) speed
Second: stdout/stderr is already successfully redirected to the textView (see otherthread in this forum).
Will think about your idea of calling the program that way but I don't see much chance.
Imagine the program is a Lisp interpreter.
