PXP(1) UNIX Programmer's Manual PXP(1) NAME pxp - Pascal execution profiler SYNOPSIS pxp [ -acdefjnstuw_ ] [ -23456789 ] [ -z [ name ... ] ] name.p DESCRIPTION _P_x_p can be used to obtain execution profiles of Pascal pro- grams or as a pretty-printer. To produce an execution pro- file all that is necessary is to translate the program specifying the z option to _p_i or _p_i_x, to execute the pro- gram, 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 _p_x_p is discussed in sec- tions 2.6, 5.4, 5.5 and 5.10 of the _B_e_r_k_e_l_e_y _P_a_s_c_a_l _U_s_e_r'_s _M_a_n_u_a_l. -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 _c_o_r_e. -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 pro- files, 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 Printed 11/26/99 1 PXP(1) UNIX Programmer's Manual PXP(1) lines are used. -w Suppress warning diagnostics. -z Generate an execution profile. If no _n_a_m_es, 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 _p_x_p to use _d spaces as the basic indenting unit. The default is 4.
