Hello,
I was wondering if anyone knew offhand if there is an SVC or system call in assembler with which a program can look up its region size (total size and/or available etc).
Thanks |

Try rummaging through the JFCB (example using R1). Not sure of the JFCB DSECT name, but it's probably in SYS1.MACLIB or SYS1.MODGEN -
| Code: |
L R1,X'21C' POINT TO 'TCB'
L R1,X'B4'(,R1) POINT TO 'JFCB'

| I am not aware of any system service that will provide what you are looking for. However the LDA control block has what you want . |
