KILL can be used to delete files from the SD card. The file must not be in use for this command to succeed. KILL takes a single argument which is the name of the file that should be deleted.
Deletes the file "hello.txt" from disk:
OUTMODE -2 KILL "hello.txt" IF LASTERR = 0 THEN PRINT "the file was successfully deleted" ELSE PRINT "something's gone wrong "; PRINT LASTERR END IF
KILL sets the pseudo variable LASTERR to report success or failure.
