IBM 5100 Communications Manual

EDIT
During the edit operation, you can edit the data in the extended display, print it,
write it
on tape, or compose a message offline (see Composing Messages Offline).
The keys used during the edit operation are activated by holding down the CMD
key and pressing a specific alphameric key:
Key
Q
Edit
CD
Line delete
CD

CD

(option T only)
Function
Starts the edit operation.
Deletes all characters on the input line to the
right of and at the cursor position.
Prints
the data stored in the extended display
from the input line to the end of the extended
display.
Restores
the data on the display screen to the
home position in the extended display.
Writes
the data stored in the extended display
on tape from the input line to the end of the
extended display.
You
must position the line to be edited on the input line by using the scroll keys
before starting
the edit operation. When you press the edit key, the first 64 character
positions of each line are displayed, and the cursor is in position 1.
During the edit operation, the delete and insert functions and the backspace and
forward space keys operate as they normally do during APL or BASIC language
operations. If you press the backspace key when the cursor is at the left edge of the
display screen (position 1) and positions 1 to 5 on the status line do not indicate
00001, all the data moves to the right. If you press the forward space key when the
cursor is at the right edge of the display screen (position 64) and an arrow is
displayed in position 64 of the status line, all the data moves to the left. Positions
1
to 5 and 64 of the status line indicate whether any data is to the left or right of
the display screen (see Communications Status Line).
After the line is edited, you can transmit it by pressing the EXECUTE or ATTN key.
All data in the extended display following the edited line is deleted. New data is
added to the extended display following the edited line.
To terminate the edit operation, press the EXECUTE, ATTN, or home (CMD and
alphameric 8) key.
If you press the home key after editing is complete, the displayed
data returns to the home position, the edited line is not transmitted, and all the data
following the edited line in the extended display is deleted as explained previously.
If you press the home key before any editing is done, the displayed data returns to
the home position and no data is lost from the extended display; therefore, you can
end the edit operation without losing any data.
