Exclusion to Prevent Control-Interval (CI) Processing and EXCP

CA Compress does not expand or compress data when invoked by a program using EXCP or Control-Interval (CI) processing. The tables *EXCLUDE-JOB-SORT, *EXCLUDE-PGM-SORT and *EXCLUDE-MOD-SORT force programs performing CI access, such as SYNCSORT, to use record management access so that the data is compressed and expanded correctly. The Physical Sequential Transparency reallocates PST data sets before giving control to SORT and other programs, in order to make them use BSAM instead of EXCP. This enables CA Compress to compress and expand logical records.
