We have a production machine running release V4R2M0 and a test machine running release V4R3M0. We changed the default on the test machine to compile all objects at release V4R2M0. We've had this arrangement for months with no problems. Now the CL compiler has stopped working. Joblogs show message CPF0814 "Licensed Program 5769-SS1 Option 9 not installed." I've asked around the shop but no one knows of any recent changes to the test machine. Any ideas?
