n 8
Moves the cursorto the left by n spaces.
If
no number n is specified, the cursor
moves backone space. When the cursormoves to the left, all characters in its
"path" are erased from the display, but
they
are
not
deleted
from
the
program
line. Using this in conjunction with 0 orK or C can give misleading Video Displays
of
yourprogram lines. So, be careful using it! For example, assuming
you've
used
nSpace-Barso that the Display shows:
100
FOR
I= 1TO
1011I
type 8 and hit the
8key.
The
display will show something like this:
100FOR
1=11III
(SHIFT)
CD
(will vary depending on number
of
blanks in
yourline 100)
Hitting
SHIFT and(l)keys togethereffects an escape from any
of
the Insert
subcommands:
x, I and H. Afterescaping from an Insert subcommand,
you'll
still
be in the Edit Mode, and the cursor will remain in its currentposition. (Hitting
(ENTER)
is another way to exit these Insert subcommands).
L (List Line)
When the Computeris in the Edit Mode, and is not currently executing one
of
the
subcommands below, hitting
L causes the remainder
of
the program line to be
displayed. Thecursordrops down to the next line
of
the Display, reprints the
currentline number, and moves to the first position
of
the line. Forexample, when
the Display shows
10011III
hitL
(without hitting
(ENTER)
key) and line 100 will be displayed:
100
FOR
1=1
TO 10 STEP.5: PRINT
I,
I [2, I
[3:
NEXT
10011III
This lets you look at the line in its current form while
you're
doing the editing.
