H[ELP]
STRING Continuous character output.
recw The number of words to be displayed per line when the code
is not disassembled. Defaults are 4 (CM) and 8 (NM).
bytew The width in bytes of the displayed values when the code is
not disassembled. Used to determine the output spacing, and
may be 1, 2 (CM default) or 4 (NM default).
DESC:
The DC (Display Code) command displays CM or NM program file code.
Library code may also be displayed based on the type of the LOGADDR
parameter (e.g., GRP(1.70), SYS(1.40)), or by using the appropriate
Display Code command variant (e.g., DCG, DCS, and so on.). By default,
disassembled code is displayed one instruction per line.
EXAMPLE:
$ nmdebug > dc FOPEN,4
SYS $a.3714f8
003714f8 FOPEN 6bc23fd9 STW 2,-20(0,30)
003714fc FOPEN+$4 37de00d0 LDO 104(30),30
00371500 FOPEN+$8 6bda3ee9 STW 26,-140(0,30)
00371504 FOPEN+$c 67d93ee5 STH 25,-142(0,30)
Display the help entry for the DC command. Notice that the two characters "DC" are a valid
hexadecimal literal, so the help facility reports that fact.
$nmdat > help dc, desc
"dc" is a NUMBER, and a COMMAND name.
cmd DC display nm cm
DESC:
The DC (Display Code) command displays CM or NM program file code.
Library code may also be displayed based on the type of the LOGADDR
parameter (e.g., GRP(1.70), SYS(1.40)), or by using the appropriate
Display Code command variant (e.g., DCG, DCS, and so on.). By default,
disassembled code is displayed one instruction per line.
$nmdat >
Display the help entry for the DC command but only show the command description.
$nmdat > help 123
"123" is a NUMBER.
Display the help text for the number "123".
Limitations, Restrictions
Topical help (for example, general help with expressions, breakpoints, and so on.) is not
supported.
Help for the window commands do not contain help text broken down by USE, PARMS, DESC,
and EXAMPLEs.
