 * Maximum screen size in visual mode.
 *
 * Because the routine "alloca" is not portable, TUBESIZE
 * bytes are allocated on the stack each time you go into visual
 * and then never freed by the system.  Thus if you have no terminals
 * which are larger than 24 * 80 you may well want to make TUBESIZE
 * smaller.  TUBECOLS should stay at 160 since this defines the maximum
 * length of opening on hardcopies and allows two lines of open on
 * terminals like adm3's (glass tty's) where it switches to pseudo
 * hardcopy mode when a line gets longer than 80 characters.
