PROF(1)			 HP-UX 5.0		       PROF(1)

     NAME
	  prof - display profile data

     SYNOPSIS
	  prof [ -a ] [ -l ] [ file ]

     HP-UX COMPATIBILITY
	  Level:    HP-UX/STANDARD

	  Origin:   System III

     DESCRIPTION
	  Prof interprets the file mon.out produced by the monitor(3C)
	  subroutine.	Under  default	modes, the symbol table in the
	  named object file (a.out default)  is	 read  and  correlated
	  with	the  mon.out  profile file.  For each external symbol,
	  the percentage of time spent executing 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 the -a option is used, all symbols	 are  reported	rather
	  than	just  external symbols.	 If the -l option is used, the
	  output is listed by  symbol  value  rather  than  decreasing
	  percentage.

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

     FILES
	  mon.out  for profile
	  a.out	   for namelist
