It's the same command that deletes any file -
From help:
"Deletes files from a disk.
Syntax
Kill pathname
The required pathname argument is a string expression that specifies one or more file names to be deleted. The pathname may include the directory or folder, and the drive.
Remarks
Kill supports the use of multiple-character (*) and single-character (?) wildcards to specify multiple files.
An error occurs if you try to use Kill to delete an open file.
Note To delete directories, use the RmDir statement."
