Software requirement for running REXX checks

More and more checks are being developed in System REXX. Because check providers use both REXX and compiled REXX for checks, you must ensure that either the SEAGALT or SEAGLPA library is available in the system search order.

• SEAGALT is provided in z/OS® V1R9 and higher
• SEAGLPA is provided in the IBM® Library for REXX on IBM z Systems product

REXX execs that are not compiled do not require the SEAGALT or SEAGLPA libraries. For more information, see:

• IBM Compiler and Library for REXX on System z: User's Guide and Reference for information about SEAGALT and SEAGLPA and writing compiled REXX code
• z/OS MVS Programming: Authorized Assembler Services Guide for information on z/OS System REXX.
