The P04 report is used for mapping source lines in USS programs. It requires the programs to have debug files in the ELF/DWARF format associated with them.
This report maps measured CPU or Wait activity to specific source lines within a CSECT. Use the "P" line command, on an eligible line command field, to launch this report. Source statements from a single compile unit are shown. A percent value is shown for source statements in which CPU activity was measured. A "P" command can be entered on the LineNo field to see the source for that line.
A sample report is shown here.
