SUBTTL HLPSTR -- The HELP string
HLPSTR: ASCIZ ~
DCNSPY uses verb-mode SCAN. The commands are:
JOB n Job number to spy on, no default
Ignored if SJBPTR is non-zero, see below.
CHANNEL n DECnet channel number for that job, default 1
CIRCUIT ckt-id Set ckt-id for examining circuit blocks.
(Circuit-ids are of the form DEV-CNT-UNT, ex. DTE-0-1)
NODE n Node number for adjacency block, default first AJB
[NO]COMMENT Type out comments for each field displayed
[NO]DPY Use DPY mode
PAGE Length by which DPY mode + and - commands shift page
DELAY Seconds to sleep in DPY mode
SJBPTR n Address of SJB to use.
While SJBPTR is non-zero, Job is ignored.
SJB Action command, type out SCTL's SJB
NRTSJB Action command, type out NRTSER's SJB
SLB Action command, type out SCTL's SLB
ELB Action command, type out NSP's ELB
RCB Action command, type out RTR's RCB for given circuit-id
AJB Action command, type out RTR's AJB for given adjacency
DLB Action command, type out DLL's DLB for given circuit-id
LNB Action command, type out DLL's LNB for given circuit-id
MEM Action command, type out memory utilization
KDP Action command, type out KMC/DUP data base
DAYTIME Action command, type out current time
In DPY mode, the immediate commands are:
escape Escape to command mode
^Z Escape to monitor mode, CONTINUE to return
^C Escape to monitor mode, CONTINUE to return
R Refresh the screen
space Recalculate the screen now
+ Move window forward by PAGE lines
- Move window backward by PAGE lines
