Appendix B MPE XL Trap Subsystem Escape Codes
The escape codes from the trap library are 32-bit integer values that are
read in two 16-bit fields:
+----------------+----------------+
| Error Number | Subsystem |
+----------------+----------------+
Bit 0 15 16 31
Bits (0:16) comprise ecode.errnum. Bits (16:16) comprise ecode.subsys.
The subsystem number for the MPE XL trap subsystem is 200. The values of
ecode.errnum are listed in Table B-1:

NOTE There are four escape codes that are associated with illegal
pointers. If you want to catch code errors due to illegal
pointers, you must check for all four escape codes:
0x000a00c8
0x000b00c8
0x003400c8
0x003500c8
