IBM Developer for z/OS code coverage fails to cover all source

Troubleshooting

Problem

When running code coverage with IBM Developer for z/OS (IDz), some source appears to have been skipped altogether and does not show up on the report as either red or green.

Symptom

The report can show that some lines are not marked as either red or green indicating they were included in the report.

Cause

If are compiling with the OPTIMIZE (OPT) option, it may effect the code coverage and result in not all code being included in the report.

Example compile parameter used:

//STP0000 EXEC PROC=ELAXFCOC,
// CICS=,
// DB2=,
// COMP=,
// PARM.COBOL=('SOURCE,LIST,XREF,MAP,LIB,OPT')
//*             'ARITH(EXTEND),DYN,F(W,W)',
//*             'TRUNC(BIN),OPT,FASTSRT')

Resolving The Problem

Remove the OPTIMIZE setting when compiling.
