screen and redisplay

I don't understand what this is all about.
I thought that clisp had no idea about screens and was just running a
top level REP loop connected to a set of character streams.

Under what circumstance would curr->image be true?

this code is specific to the SCREEN package (window streams).
it is of no interest to you if you are not using that.

Is this the one you said was removed in 1999 or is there some other
screen package?  I see screen listed in impnotes 32.1.

You misread me.
I said that Bruno removed (in 1998) the _editor_ based on screen, not screen 
itself.
