126 The Built-in Software
To issue a COLOR command, enter command mode and type COLOR and
the number of the color you want for the screen background. Type a semicolon at
the end of the command.
When you switch to another program, the screen color change remains in
effect.
When you select a new color, cell entries that were made previously are not all
automatically changed to the new character color (if there is a new character
color). To change the cell colors, just pass the cell cursor up and down one
column. All the cells in each row are changed to the new character color as the cell
cursor passes down the column.
All the characters in the word processor work area, however, are automatically
changed to a new character color as soon as you switch to the word processor.
COPY SS
Lets you copy a cell entry into the cell where the cell cursor is currently located.
If there is already a value in the recipient cell, it is overwritten unless it is protected
by the FRE (frozen cell) command. The cell that is being copied is not affected by
the COPY command; this is a duplication, not a transfer.
To use the COPY command, move the cell cursor into the cell where you want
the duplicate entry to appear. Then type the COPY command followed by the cell
number of the cell you are copying.
The COPY command does not adjust formulas when the cell is copied. If the
duplicate cell is used in a formula that needs adjustment, you must change the
formula manually.
Example: copy3;4 Copies the entry from cell 3;4 into the cell where the cell cursor
is currently located.
DF WP, SS
Removes a file permanently from a disk. Use the DF (Delete File) command
only when you no longer want to keep a copy of the file.
• To delete a file you previously saved on disk, issue the DF command and type
the name of the file when the prompt DELETE FILE: is displayed on the
command line at the bottom of the work area. When you press RETURN, the
disk takes a few seconds to remove the file from the disk. This command operates
like the SCRATCH command in BASIC.
You can verify that the file has been deleted by viewing the disk catalog, which
you access by issuing a CA command.
