Introduction to Programming

Chapter 10

10-11

When programming a slash “/” followed by a numeric value (1-9)

anywhere in a block, the control skips (does not execute) all remaining

programmed commands if you turn on the block delete feature. Turn on

this feature by pressing the {FRONT PANEL} softkey, or by activating the

installed switch (optionally) on the MTB panel. If you use the {FRONT

PANEL} softkey, only block delete /1 is available.

Your system installer determines in AMP i f the entire block is deleted or if

only the characters to t he right of the block delete / are deleted. If the

entire block is to be deleted, it is done regardless of the position of the /

character in the block.

The control always reads several blocks into its buffer memory so that it

can prepare for moves and commands before it executes them. The switch

(or softkey) controlling a block delete must be set before

that block is read

into buffer memory. Otherwise, it is not skipped.

The control considers a “/” without a number to mean “/1”. However, you

must program a “/1” if you use more than one block delete number in a

block.

The block delete is active for sequence number search and dry run

operations.

The control ignores the block delete when loading a part program from

tape or other device i nto control memory. The control also ignores the

block delete when a part program is saved on punched tape or other device

from control memory.

For details on the block delete switch(es), see the PAL Reference manual

and the documentation prepared by your system installer.
