Re: Pausing compilation in GForth

[paul . ortais]

Thank you Anton, for your quick answer,

> 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  :-)
