Deleting a Subroutine Program File
All created program files (file numbers 3 – 255) can be deleted. You cannot
delete files 0 and 1. Deleting file 2 deletes all ladder rungs in the main
program file. Attempting to delete file 0, file 1, or an undefined subroutine
file displays the
FILE CANNOT BE DELETED! prompt. In the case of a
subroutine file, the error message indicates that a subroutine program file of
a higher number exists.
