Hi, You can verify what changes have occured by looking in the $DBGMT/dynamic_debug/control file, and verifying what statements have been matched. For example, we add a 'p' when printing is enabled. Does that address your concern? As these debug statements come and go, I think I'd prefer not to error out in this case.
