Screen Editing
One of the most powerful features of the VIC 20 is its screen editor. The
key to using the VIC 20's editing capabilities
is the cursor. You can move the
cursor in four directions: up, down, left, and right. You can also insert or
delete characters anywhere on the screen,
or even clear the entire screen
using a single keystroke.
EDITING TEXT ON THE CURRENT DISPlAY UNE
Occasionally, you may notice a mistake on a line you are currently
entering. You can correct mistakes on a line you are entering by backspacing
to the error and correcting it.
For example,
OUR BUDGEY
was intended to display as OUR BUDGET. You can change the Y to a T
easily enough. Type in the line above and use the
SHIFT and CURSOR
LEFT/RIGHT keys to position the cursor over the Y.
OUR BUDGE.,.
OUR BUDGET.
To change the Y to a T, simply type T. This replaces the old letter and
moves the cursor one position to the right.
BACKSPACING WITH THE DELETE KEY
If you just entered a character that you would like to retype, press the
INST / DEL key to remove the incorrect character, and then continue typing.
When you used the
CRSR LEFT/ RIGHT key, the cursor simply moved over
the characters on the screen without changing them. Try the following
example using the
INST / DEL key:
OUR BUDGE.
OlJR BUDGET.
