Thank you Anton, for your quick answer,
I didn't think to this, because I don't want the whole screen to be refreshed.
My screen is 270 columns wide (and 68 lines), and during the compilation I build pseudo-graphic structures in columns >80, and of course I want to keep them while the comiler run over some twenty screens.
So, I only have <80 columns source lines, which is comfortable. I want a max 65 lines to compile then check the result in progress on the rigtht side. Simulating a sort of two-screen display, or a source and target one.
when I am done checking and want to resume compiling, I wipe the blackboard at left like:
0 0 at-xy 65 0 do 79 0 do space loop loop
and resume compilation.
Maybe there are Lmargin and Rmargin tricks there...
Well, had I a magic wand :-)

Hello all,
I am looking for any method to pause compilation, so that it goes on by
smaller chunks and I have the time to examine successes and errors, then
release it for one more screen etc.
Tried to insert prompts like key, key?, ekey? so that I hit eg the
spacebar or down arrow to release it and run, but that seems to
interfere with the flow, and halt it.
Idea anyone?
I think what you want is more.fs: Start Gforth with, e.g.
gforth more.fs myfile.fs
and it will stop and prompt after outputting a screenful, and any key
will get you the next screen.
It works in Gforth 0.7, but is broken at the moment in the development
version.
