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 necessary 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.

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.
