Hello, I am trying to clean up in incremental-redisplay.lisp. Here is what I suggest for now. If someone has objections, let me know: * get rid of *enable-updating-output*. It is initialized to t in incremental-redisplay.lisp and used there as well as in frames.lisp, but it is never set or bound. I suppose it was meant to be some kind of debugging tool, * get rid of redisplay-add-output-record and redisplay-delete-output-record which are never called, * get rid of clear-moved-record which is never called. What do you think? -- Robert Strandh --------------------------------------------------------------------- Greenspun's Tenth Rule of Programming: any sufficiently complicated C or Fortran program contains an ad hoc informally-specified bug-ridden slow implementation of half of Common Lisp. ---------------------------------------------------------------------
