HC79102 is HOLDDATA information.
The problem it highlights is solved by ptf RO93739.
To resolve this, you can code BYPASS(HOLDSYSTEM,HOLDERROR). in AGJ5APP:
//SMPCNTL DD *
SET BOUNDARY (CAIT18) .
CAGJJ00 /*CA IDMS Base Option */
CAGJJ01 /*CA IDMS CICS Support */
This should get you by the HOLD error, and then you can apply RO93739.
