12.12 OPTIONAL BLOCK SKIP
When a slash and number ( /n) is programmed at the head of a program,
and when the machine is operated with the optional block skip switch n
on the machine operator's panel on, information in the block
commanded with the /n corresponding to the switch number n is
ignored.
If the optional block skip switch n is turned off, information in the /n
commanded block will not be ignored. The block with /n commanded
can be skipped by the operator's selection.
I can be used for n. The 1 to /1 can be omitted.
Example) /1 N12345 G00 X100.Y200.;
12.13 ADDITIONAL OPTIONAL BLOCK SKIP
2 to 9 can also be used for the n of the /n.
12.14 TAPE HORIZONTAL (TH) PARITY CHECK AND TAPE
VERTICAL(TV) PARITY CHECK
A parity check is made on the number of punch holes for each input
tape character.
If the parity does not match, an alarm occurs (TH check). A parity
check is made on each input data block. If the number of characters in
one block (from the code next to EOB to another EOB) is odd, an alarm
occurs (TV check). The TH or TV check cannot be made on the area
skipped by the label skip function.
The TH check is not made on the command field. A parameter can be
used to specify whether the characters constituting comments are to be
counted when obtaining the number of characters for TV check. The
TV check function is validated or invalidated according to the value set
on the MDI panel.
