ED
Puts Editor at end of last program
:ED 5
Puts Editor at line 5
:ED #BEGIN
Puts Editor at label #BEGIN
Line numbers appear as 000,001,002 and so on. Program commands are entered following the
line numbers. Multiple commands may be given on a single line as long as the total number of
characters doesn't exceed 80 characters per line.
While in the Edit Mode, the programmer has access to special instructions for saving, inserting
and deleting program lines. These special instructions are listed below:
Edit Mode Commands
<RETURN>
Typing the return key causes the current line of entered instructions to be saved. The editor will
automatically advance to the next line. Thus, hitting a series of <RETURN> will cause the editor
to advance a series of lines. Note, changes on a program line will not be saved unless a <return>
is given.
<cntrl>P
The <cntrl>P command moves the editor to the previous line.
<cntrl>I
The <cntrl>I command inserts a line above the current line. For example, if the editor is at line
number 2 and <cntrl>I is applied, a new line will be inserted between lines 1 and 2. This new line
will be labeled line 2. The old line number 2 is renumbered as line 3.
<cntrl>D
The <cntrl>D command deletes the line currently being edited. For example, if the editor is at line
number 2 and <cntrl>D is applied, line 2 will be deleted. The previous line number 3 is now
renumbered as line number 2.
<cntrl>Q
The <cntrl>Q quits the editor mode. In response, the DMC-1600 will return a colon.
After the Edit session is over, the user may list the entered program using the LS command. If no
operand follows the LS command, the entire program will be listed. The user can start listing at a
specific line or label using the operand n. A command and new line number or label following the
start listing operand specifies the location at which listing is to stop.
Example:
Instruction Interpretation
:LS
List entire program
:LS 5
Begin listing at line 5
:LS 5,9
List lines 5 thru 9
:LS #A,9
List line label #A thru line 9
:LS #A, #A +5
List line label #A and additional 5 lines
Program Format
A DMC-1600 program consists of DMC-1600 instructions combined to solve a machine control
application. Action instructions, such as starting and stopping motion, are combined with
DMC-1600
