Hi Not so serious problem, in z/OS 1.13 we wrote our SYSADATA to PDSE and using 0M region size. In z/OS 2.1 all this jobs ended with an S0F4 reason x'24' and i/O error with SYSADATA After a PMR it turned out that the PDSE has not enough storage. We are using the default assembler OPTION SIZE(MAX) . In this case , according the book , the assembler gives back 128 K byte storage, but it is not big enough for PDSE. I will change the default SIZE, but maybe the assembler would gives back something more as 128K ?
