NAME
       pxp - Pascal execution profiler

SYNOPSIS
       pxp [ -acdefjnstuw_ ] [ -23456789 ] [ -z [ name ... ] ] name.p

DESCRIPTION
       Pxp can be used to obtain execution profiles of Pascal programs or as a pretty-printer.	To produce an execution profile all that is neces-
       sary is to translate the program specifying the z option to pi or pix, to execute the program, and to then issue the command

	    pxp -z name.p

       A reformatted listing is output if none of the c, t, or z options are specified; thus

	    pxp old.p > new.p

       places a pretty-printed version of the program in `old.p' in the file `new.p'.

       The use of the following options of pxp is discussed in sections 2.6, 5.4, 5.5 and 5.10 of the Berkeley Pascal User's Manual.

       -a    Print the bodies of all procedures and functions in the profile; even those which were never executed.

       -c    Extract profile data from the file core.

       -d    Include declaration parts in a profile.

       -e    Eliminate include directives when reformatting a file; the include is replaced by the reformatted contents of the specified file.

       -f    Fully parenthesize expressions.

       -j    Left justify all procedures and functions.

       -n    Eject a new page as each file is included; in profiles, print a blank line at the top of the page.

       -s    Strip comments from the input text.

       -t    Print a table summarizing procedure and function call counts.

       -u    Card image mode; only the first 72 characters of input lines are used.

       -w    Suppress warning diagnostics.

       -z    Generate an execution profile.  If no names, are given the profile is of the entire program.  If a list of names is given, then  only
	     any specified procedures or functions and the contents of any specified include files will appear in the profile.

       -_    Underline keywords.

       -d    With d a digit, 2 <= d <= 9, causes pxp to use d spaces as the basic indenting unit.  The default is 4.

DIAGNOSTICS
       For a basic explanation do

	      pxp

       Error  diagnostics  include  `No  profile  data in file' with the c option if the z option was not enabled to pi; `Not a Pascal system core
       file' if the core is not from a px execution; `Program and count data do not correspond' if the	program  was  changed  after  compilation,
       before profiling; or if the wrong program is specified.
