When transferring a file to the Z/OS (MVS) Agent via a JOBF, the transfer fails with:
U00011402 Cannot open file 'JOBF.NAME'. Error code: '121(EDC5121I Invalid argument.)', error description: 'svc99 0h/lastop 0'.
Improper Configuration of JOBF
Release : 12.3
Component : AUTOMATION ENGINE
Review the configuration of the JOBF, to make sure it is using the syntax and commands available to LCE or TSO, not combining both. In the example above:
fopen(//'JOBF.NAME',wb,RECFM=FB,LRECL=1200,BLKSIZE=0,UNIT=VIRTUAL,RETPD=99000)

This is using a combination of LCE and TSO Allocate syntax which is causing the failure.
