The DEL Function
Key
6-10 Programming Special Functions
The DEL (DELete) function key erases a program or subroutine. To begin
the DEL operation, first place the cursor on the program or subroutine
which is to be deleted. Once the cursor is positioned, press the DEL (F7)
function key. This will cause either of the following prompts to appear on
the screen:
DELETE SFPGM {number} : ARE YOU SURE
DELETE SFSUB {number} : ARE YOU SURE
The function keys shown at the bottom of the screen will change to a NO for
the F1 function key and a YES for the F2 function key. If the NO function
key is pressed, the DEL operation will halt and the original menu will
appear. If the YES function key is pressed, the DEL operation will proceed
and the subroutine or program will be destroyed. After the DEL operation
has completed, the previous menu will appear on the screen.
