Request to implement ^S and ^Q in the interactive session.
In a Linux terminal, when something is scrolling too fast you can always press Control-S (meaning stop) to freeze the display
so you can see what happening, and scroll up/down, then you press Control-Q (meaning continue) and it will resume.
Those 2 signals are actually ignored by the actual interactive apl interface. (to be proven, not sure at 100%)
My guest is that if they were not ignored, the default will actually do the job (suspend and resume) without any programming changes.
I may be wrong.
Xtian.
you can test it on Linux by issuing "cat `a *very large file*`" and typing Control-S (to stop) .... then Control-D (to resume) displaying.
