System Debug Windows
Gr - The NM General Registers Window
• Q - The current Q value (stack frame), expressed in CM words, relative to DB.
• S - The current S value (TOS), expressed in CM words, relative to DB.
• CMPC - The current CM program location, expressed as a logical code address. This
includes the library (PROG, GRP, PUB, LGRP, LPUB, SYS), logical segment number,
and program counter in CM words, relative to the base of the current code segment.
• CIR - The current instruction register.
• MAPFLAG - If 0, the current CM segment is logically mapped. If 1, the current CM
segment is physically mapped. This is used for CM CST expansion.
• MAPDST - The mapping DST number for CM CST expansion.
Gr - The NM General Registers Window
The NM register window displays the current values of the Native Mode General
Registers.

• GR$ - Abbreviation for the window and the current output display. This window is
always displayed in hexadecimal.
• ipsw - The current processor status word contents. The numeric value as well as the
decoded bits are displayed. (Refer to the conventions pages for a description of the
format for this value).
• priv - The current privilege level. This is based on the two low-order bits of the PCOF
register.
• pc - The current program counter. This is a combination of the PCSF and PCOF
registers. The offset part is always displayed word aligned.
• pin - The process identification number (PIN) for the current process.
window body line(s)
• r0 - r31 - The current values of the general registers.
Sr - The NM Special Registers Window
The special register window displays the current values of special NM registers.
