Storing REXX Execs in VLF Storage

The author of the REXX exec can control whether a REXX exec allocated to a SYSPROC system-level or application-level CLIST library is to be compressed. In general, compression strips comments and leading and trailing blanks. Blank lines are replaced with null lines. Details on file compression restrictions for REXX are explained below.

Note: Automatic compression governed by the occurrence or non-occurrence of SOURCELINE in an exec can be overridden by explicit use of a compression indicator. You can specify either COMMENT or NOCOMMENT in a special comment in line 1 of the exec, as described in Controlling REXX Exec Compression to control compression.

When the system compresses a REXX exec, it removes the comment text and leaves the beginning and ending comment delimiters.
