C Subcommand
The C subcommand changes the next n characters to the specified character(s).
If
no
integer is specified, the character immediately to the right
of
the cursor
is
changed.
The syntax
of
the C subcommand is:
[integer] C character [character ... ]
In our previous example, line 40 was reduced to:
40
PRINT "UNDEFINED
SET";A;
8
This can be changed to print
"REDEFINED
SET"
with C:
Move
the
cursor to:
40
PRINT.
Enter
(2C)
RE
(L)
40
PRINT "REDEFINED
SET";
A;8

Q Subcommand
The Q subcommand restores the original line, as it was prior to editing,
and
leaves
the editing mode. Note
that
if
an
instruction
is
edited with Q, the changes are lost.
This subcommand returns the user
to
the command mode without executing an
edited command. This subcommand only works when editing program lines.
A Subcommand
The A subcommand restores the original line and prints the original line number
below. Editing
is
restarted. This subcommand only works when editing program
lines.
When the A subcommand
is
used with the previous example, the result
is:
40
PRINT "UNDEFINED
SET".
Enter (A) (L)
40
IF
A>B THEN
120
ELSE
"NULL
SET"
40.
E Subcommand
The E subcommand exits the editing mode. The edited line replaces the original line.
When the E subcommand
is
used with the previous example, the result
is:
40
PRINT "UNDEFINED SET"
(The E subcommand is entered)
Carriage
Return
A Carriage Return exits the editing mode,
and
prints
the rest
of
the line being edited.
The edited line replaces the original line.
