Daniel,
Your statement contradicts this from the section "Overview - Test Coverage" / "Restrictions when using test coverage" from the Visual COBOL documentation (my emphasis):
We recommend that you do not use test coverage in a production system because of the increased requirements on system resources when running in test coverage mode. However, you can compile TESTCOVER into your production system if needed.
Also, as I usnderstand it test coverage mode needs to be enabled using the TESTCOVER environment variable.
The comment above comes from the VC for Eclipse (Windows). I notice that the entire "Test Coverage" section is missing from the VC for Eclipse (UNIX) documents.
Leigh.
