Characters can also be erased in the input area (lines 1-2 on the screen)
before being sent to the program display area. Delete the character to the
left of the cursor on the input line by pressing the [DEL] key. Delete all
information on the input line by processing the [DEL] key while holding
down the [SHIFT] key. A new character will be inserted to the left of the
cursor automatically when any character key is pressed. The cursor can be
moved on the input line by holding down the [SHIFT] key and pressing the
left or right cursor keys.
Each block in a part program can be assigned up to a five-digit numeric
value following an N address. These numbers are referred to as sequence
numbers and are used to distinguish one block from another.
Sequence numbers can be assigned at random to specific blocks or to all
blocks if desired. Blocks assigned sequence numbers can be called later by
designating their sequence number.
Sequence numbers can be renumbered or assigned in 3 ways:
Manually type in a sequence number following an N word for each
block individually.
assign new sequence numbers only to blocks that already have sequence
numbers
assign new sequence numbers to all blocks
