CLR
—Clear program variables
CLR
This statement erases any variables in memory, but leaves the pro
gram intact. This statement is automatically executed when a RUN
or NEW command is given. CLR is not automatically executed after
editing because variables and text no longer share memory.
U
CMD
—Redirect screen output
CMD logical file number [,write list]
This command sends the output, which normally goes to the screen
(i.e., PRINT statement, LIST, but not POKES into the screen) to
another device, such as a disk data file or printer. This device or file
must be OPENed first. The CMD command must be followed by a
number or numeric variable referring to the file. The write list can be
any alphanumeric string or variable. This command is useful for
printing headings at the top of program listings.
EXAMPLE:
OPEN 1,4
CMD1
LIST
PRINT#1
CLOSE 1
OPENS device #4, which is the printer.
All normal output now goes to the printer.
The LISTing goes to the printer, not the
screen—even the word READY
Sends output back to the screen.
Closes the file.
\ J
COLLECT
—Free inaccessible disk space
COLLECT [Ddr i ve number][< ON |, > Udevice]
Use this command to make available any disk space that has been
allocated to improperly closed (splat) files, and to delete references
to these files from the directory. Splat files are files that appear on
the directory with an asterisk next to them. Defaults to device
number 8.
EXAMPLE:
COLLECT DO
Free all available space which has been
incorrectly allocated to improperly closed
files.
