I just noticed something I had not noticed before.
I have a little test program that I am doing all sorts of things to see
how things work. So, of course, I am crashing it a lot. Sometimes even
on purpose using DC x'0000' instructions.
What I have noticed is that the log shows the registers differently
sometimes. For example:
SYSTEM COMPLETION CODE=0C1 REASON CODE=00000001
TIME=00.40.10 SEQ=00137 CPU=0000 ASID=0034
PSW AT TIME OF ERROR 078D0000 00008CD8 ILC 2 INTC 01
ACTIVE LOAD MODULE ADDRESS=00007000 OFFSET=00001CD8
NAME=COPYTPX
DATA AT PSW 00008CD2 - 4710B03A 00004D10 B0308F00
GR 0: 00000000_00009018 1: 00000000_0000901F
2: 00000000_00007604 3: 00000000_0000AFFC
4: 00000000_00009018 5: 00000000_0000901F
6: 00000000_00040000 7: 00000000_FD000000
8: 00000000_00009010 9: 00000000_80008036
A: 00000000_0000AFE0 B: 00000000_00008CB0
C: 00000000_40008010 D: 00000000_00008E98
E: 00000000_000092A8 F: 7FFAEA00_00008CB0
vs. the following:
SYSTEM COMPLETION CODE=0C1 REASON CODE=00000001
TIME=00.39.24 SEQ=00136 CPU=0000 ASID=0034
PSW AT TIME OF ERROR 078D0000 00008CE4 ILC 2 INTC 01
ACTIVE LOAD MODULE ADDRESS=00007000 OFFSET=00001CE4
NAME=COPYTPX
DATA AT PSW 00008CDE - 8DE00A13 000047F0 B0A29680
GR 0: 00000950 1: 009C36B0
2: 00007604 3: 0000AFFC
4: 00009018 5: 0000901F
6: 00040000 7: FD000000
8: 00009010 9: 80008036
A: 0000AFE0 B: 00008CB0
C: 40008010 D: 00008E98
E: 000092A8 F: 00000000
The only difference is that 64 bit regs are shown if I have not done an
OPEN macro while 31 bit registers are shown if I have issued an OPEN macro.
Test code snipit:
*DC X'0000'
OPEN (SNAPDCB,(OUTPUT))
DC X'0000'
The program in question is assembled AMODE=24,RMODE=24.
OK, whats up with this?
