Running TLMS to CA 1 conversion job TMSTLMS1 to extract the VMF into Common EARL Format fails with Abend S013-20 for the VMF (TAPEDB).
This can be caused by using the CA EARL Copybook Library CTAPECPB from CA 1. The EARLDEFS from the CA 1 CTAPECPB Library use TMSEARL, which tries to open the VMF (TAPEDB) using the DCB attributes from the TMC, resulting in Abend S013-20.
Specify the CTAPECPB Library from TLMS in TMSTLMS1:
//EARLJCL PROC EARLCPB='CAI.CTAPECPB', <- TLMS CTAPECPB
The EARLDEFS from the TLMS CTAPECPB use TLMSEARL to read the VMF with the correct DCB attributes.
