PXP(1) General Commands Manual PXP(1)
pxp - Pascal execution profiler
pxp [ -acdefjnstuw_ ] [ -23456789 ] [ -z [ name ... ] ] name.p
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.

Berkeley Pascal User's Manual
For a basic explanation do
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.
