System Debug Windows
P (nmP) - The NM Program Window
window.
• PROG 0.1667 - The logical code address for the CM program counter. If the window does
not contain the CM program counter, then the value is the logical code address of the
first line in the window. In our example, the CM program counter is currently at a
program file, logical segment number 0, at an offset of 1667 words. Other possible
logical segment types are GRP, PUB, LPUB, LGRP, SYS.
• (E) - The segment is (E) emulated or (T) translated.
• SEG' - The segment name for the current segment being displayed.
• CSTX 1 - The CSTX (or CST) absolute segment number.
• Level 0 - The current stack level. (Refer to the LEV command.)
window body line(s)
• offset: - The CM word offset (segment relative) for the instruction line which is being
displayed.
• breakpoints - Breakpoints are displayed between the offset and instruction. Refer to the
conventions pages for a description of all possible breakpoint notations.
[1] process local breakpoint, index number 1
T|2| process local temporary breakpoint, count not exhausted yet, index
number 2.
• > - Flags the current program counter location.
• procedure-name+offset - The symbolic procedure name and the CM word offset
within the procedure.
• instruction (numeric, ASCII) - The instruction value is displayed formatted in the
current output base for the window, and then displayed as two ASCII characters (for
literals).
• instruction (disassembly) - The disassembled instruction value.
P (nmP) - The NM Program Window
The NM program window tracks the NM program counter (PC), displaying the
instructions that are being executed. The banner line gives information for the first
address displayed in the program window.
