Display DST 77.0, for 20 words, in hexadecimal.
Display the data as bytes (1), CM 16-bit words (2), and NM 32-bit words (4).
Note that the offset addresses are displayed in octal (the current output base), while the
data is displayed in hexadecimal, as requested.
$nmdebug > dsec 1.0,4,a
SEC $1.0 ASCII ..HP ESYS ..]@ ....
Display secondary storage at the disk address 1.0 (LDEV=1, byteoffset=0). Display four
words in ASCII. This example displays a portion of the volume label.
%cmdebug > da %1114,3,a
ABS+%1114 ASCII 82 04 9
%cmdebug > da %1474,3,a
ABS+%1474 ASCII 9 82 04
Two examples that display CM ABS relative. Both examples display three words in ASCII.
ABS is CM Bank 0 low core memory. CM SYSGLOB starts at ABS+%1000.
The first example displays the SEL release ID in the form:
uu ff vv .
The second example displays the MPE/iX system version ID in the form:
vv uu ff .

REAL $00603500 $ 80000000 0000000a 00728000 02400000
The logical code address of PC is SYS $a.728304, which translates to real memory address
c18304.
This example displays the 4-word PDIR entry in real memory for the page that contains
PC.
Display real memory (DZ) at the address TR0 (start of PDIR) plus the offset to entry, which
