Enabling REXX for CICS
The REXX Development System for CICS® and the REXX Runtime Facility for CICS are two licensed programs collectively referred to as REXX for CICS. With REXX for CICS, you can write and run REXX programs in a CICS region.
These programs have access to most EXEC CICS API commands, the CICS CEDA and CEMT transactions, and Db2® databases through the EXEC SQL interface.
