  Here is a copy of a sort of generic viewing routine incorporating most of
the VT100 keyboard commands, including home/end and pgup/pgdn.

  You will, of course, need to modify the parameters and such to fit your own
needs. As a rule, I use this as a pattern for viewing routines, adjusting as
required for the type of material being displayed.

  Good luck,
