Problem conclusion
File Manager has been modified to provide optimization options for scrambling when REPEAT or RANDOM is defined for various fields in the TO template. The new optimization option OPSCRAM can be specified as follows: 1. Installation options module (default off). 2. Providing a $$FILEM SET OPSCRAM=OFF|ON|MAX statement in JCL. 3. Selecting the required optimization option on the COPY TO panel The default behaviour is OPSCRAM=OFF. See the documentation changes for more details.
