C (Change)
Tells the Computer to let you change the specified number of characters
beginning at the current cursor position. If you type C without a preceding
number, the Computer assumes you want to change one character. When you
have entered
n
number of characters, the Computer returns you to the Edit
Mode (so you're not in the
nC
Subcommand). For example, using line 100,
suppose you want to change the final value of the FOR-NEXT loop, from " 10"
to " 15". In the Edit Mode, space over to just before the "0" in "10".
100 FOR I=1 TO 1_
Now type C. Computer will assume you want to change just one character.
Type 5, then hit L. When you list the line, you'll see that the change has been
made.
100 FOR I=1 TO 15 STEP .25 : NEXT : END
would be the current line if you've followed the editing sequence in this
chapter.
The
←
←←
←
does not work as a backspace under the C command in Edit mode.
Instead, it replaces the character you want to change with a backspace. So it
should not be used. If you make a mistake while typing in a change, Edit the
line again to correct it, instead of using
←
←←
←
.
n
S
c
(Search)
Tells the Computer to search for the nth occurrence of the character c, and
move the cursor to that position. If you don't specify a value for n, the
Computer will search for the first occurrence of the specified character. If
character c is not found, cursor goes to the end of the line. Note: The
Computer only searches through characters to the right of the cursor.
For example, using the current form of line 100, type EDIT 100 (
[ENTER]
)
and then hit
2S
:
. This
tells the Computer to search for the second occurrence
of the colon character. Display should show:
100 FOR I=1 TO 15 STEP.25 : NEXT _
You may now execute one of the subcommands beginning at the current
cursor position. For example, suppose you want to add the counter variable
after the NEXT statement. Type I to enter the Insert subcommand, then type
the variable name, I. That's all you want to insert, so hit SHIFT
↑
↑↑
↑
to escape
from the Insert subcommand. The next time you list the line, it should
appear as:
100 FOR I=1 TO 15 STEP.25 : NEXT I : END
