Define a new CICS transaction ID named XYZ, make it call exec TESTEXEC when it is started, then take the
following steps:
1. Create TESTEXEC in the RFS or in a VSE Librarian sublibrary.
2. Under REXX/CICS REXXTRY utility enter command DEFTRNID XYZ TESTEXEC and exit the REXXTRY
utility.
3. Under RDO, CEDA DEFINE TRAN(XYZ) PROGRAM(CICREXD) TWASIZE(32) GROUP(REXXCICS) and install
TRAN(XYZ) GROUP(REXXCICS).
Note: TWASIZE is required on CEDA define
4. Clear the screen and type CICS transaction identifier XYZ and press ENTER. The TESTEXEC exec
should now run.
Notes

startup.
2. The transaction ID has to be defined (by CEDA) to invoke the supplied CICREXD program.
