Let me encourage those who would code something like this for themselves--
be sure that you use the pager specified by  $PAGER  if such there be.  This
code does, to its credit.

You can probably simplify the code some with something like

	popen( " [ \"$PAGER\" ] && ( $PAGER || true ) || /usr/ucb/more ", w )

which does much of the testing of cases, at the expense of execution time.
If you aren't going to do it often, or if the user is going to spend a fair
amount of time in the file, it's probably OK, and it allows you to use the
shell instead of programming all the cases yourself.
