Commands:
All commands consist of 3 uppercase letters. If further info is required
then a * prompt is printed on a new line, where you will enter the data.
All numbers are OCTAL (3/6 digits with leading zeros). Since a teletypewriter
is being used, there is no cursor. Do NOT press Enter except after these
commands, otherwise things get confusing.
LOC - set current location pointer (the CLP)
DLP - display CLP
DPS - dump symbolic
LDO - load octal
DPO - dump octal
LBF - load BNPF format
DBF - dump BNPF format
EDT - enter Edit Mode
XQT - initiate program execution
CPY - copy routine
TRN - translate routine
SBP - set breakpoint
CBP - clear breakpoint
PRG - program PROM
Pressing Ctrl-A will escape back to the monitor. You will see 8 dashes.
Commands in the Edit Mode:
When you enter the Edit Mode it displays the CLP followed by a slash.
nnn - enter a new value into this memory location and increment the CLP
` (tic) - decrement CLP
@ - same as XQT
R - return to monitor
*nnnnnn - change CLP to this value
space - display current contents of memory
While in 'space' mode, press a letter to increment CLP, or shift-delete
(underscore character) followed by a new byte for this location.
