       prof - display profile data

       prof  [ -a ] [ -l ] [ -n ] [ -z ] [ -s ] [ -v [ -low [ -high ] ] ] [ a.out [ mon.out ... ]

       Prof interprets the file produced by the monitor subroutine.   Under  default  modes,  the
       symbol table in the named object file (a.out default) is read and correlated with the pro-
       file file (mon.out default).  For each external symbol, the percentage of time spent  exe-
       cuting  between	that  symbol and the next is printed (in decreasing order), together with
       the number of times that routine was called and the number of milliseconds per  call.   If
       more than one profile file is specified, the output represents the sum of the profiles.

       In  order  for the number of calls to a routine to be tallied, the -p option of cc, f77 or
       pc must have been given when the file containing the routine was  compiled.   This  option
       also arranges for the profile file to be produced automatically.

       Options are:

       -a     all symbols are reported rather than just external symbols.

       -l     the output is sorted by symbol value.

       -n     the output is sorted by number of calls

       -s     a  summary  profile  file  is produced in mon.sum.  This is really only useful when
	      more than one profile file is specified.

       -v     all printing is suppressed and a graphic version of the profile is produced on  the
	      standard output for display by the plot(1) filters.  When plotting, the numbers low
	      and high, by default 0 and 100, may be given to cause a selected percentage of  the
	      profile to be plotted with accordingly higher resolution.

       -z     routines	which  have zero usage (as indicated by call counts and accumulated time)
	      are nevertheless printed in the output.

       mon.out	for profile
       a.out	for namelist
       mon.sum	for summary profile

       monitor(3), profil(2), cc(1), plot(1G)

       Beware of quantization errors.

       Is confused by f77 which puts the entry points at the bottom of subroutines and functions.
