Prerequisites for Using Option 2.4

Allocate these libraries before you use option 2.4:

• Allocate your REXX source program library to SYSEXEC DDNAME.
• Allocate your REXX compiled program library to OPSCOMP DDNAME. Concatenation of multiple libraries will cause an error. Make sure that this library is a partitioned data set with these attributes:

  RECFM

  Fixed block (mandatory).

  LRECL

  4096 (mandatory)

  BLKSIZE

  4096 or greater (must be a multiple of 4096)

  DIRECTORY BLOCKS

  User-defined (dependent on number of programs)

  SPACE

  User-defined (dependent on number of programs)

• Also allocate the OPSCOMP library to the OPSEXEC concatenation

Note: The OI command uses OPSEXEC DDNAME to search for a compiled REXX program. If the program is not found in the OPSEXEC library or libraries, the SYSEXEC library is scanned next. Concatenation is allowed in the OPSEXEC library.
