| 16 | Commands: |
| 17 | All commands consist of 3 uppercase letters. If further info is required |
| 18 | then a * prompt is printed on a new line, where you will enter the data. |
| 19 | All numbers are OCTAL (3/6 digits with leading zeros). Since a teletypewriter |
| 20 | is being used, there is no cursor. Do NOT press Enter except after these |
| 21 | commands, otherwise things get confusing. |
| 22 | |
| 23 | LOC - set current location pointer (the CLP) |
| 24 | DLP - display CLP |
| 25 | DPS - dump symbolic |
| 26 | LDO - load octal |
| 27 | DPO - dump octal |
| 28 | LBF - load BNPF format |
| 29 | DBF - dump BNPF format |
| 30 | EDT - enter Edit Mode |
| 31 | XQT - initiate program execution |
| 32 | CPY - copy routine |
| 33 | TRN - translate routine |
| 34 | SBP - set breakpoint |
| 35 | CBP - clear breakpoint |
| 36 | PRG - program PROM |
| 37 | |
| 38 | Pressing Ctrl-A will escape back to the monitor. You will see 8 dashes. |
| 39 | |
| 40 | Commands in the Edit Mode: |
| 41 | When you enter the Edit Mode it displays the CLP followed by a slash. |
| 42 | |
| 43 | nnn - enter a new value into this memory location and increment the CLP |
| 44 | ` (tic) - decrement CLP |
| 45 | @ - same as XQT |
| 46 | R - return to monitor |
| 47 | *nnnnnn - change CLP to this value |
| 48 | space - display current contents of memory |
| 49 | |
| 50 | While in 'space' mode, press a letter to increment CLP, or shift-delete |
| 51 | (underscore character) followed by a new byte for this location. |
