Important: When the miscellaneous function lock feature is activated, the

control ignores M, B, S, and T words in the part program with the

exception of M00, M01, M02, M30, M98, and M99. This feature is

described on page 7-2.

2nd Miscellaneous Function (B Word)

Your system installer can use the 2nd miscellaneous functions to

distinguish a set of miscellaneous functions from the normal M code

miscellaneous functions. This manual assumes the B word is used to call

second auxiliary functions. Any alphabetic character which is not used for

other functions can be used instead of B by setting the proper AMP

parameter. For details, see documentation prepared by your system

installer, or the AMP reference manual.

The B word is designated by a two or three-digit numeric value following

address B. Unlike M codes, each block can contain only one B word.

Important: When the miscellaneous function lock feature is activated, the

control ignores M, B, S, and T words in the part program with the

exception of M00, M01, M02, M30, M98, and M99. This feature is

described on page 7-2.

Each block in a part program can be assigned up t o 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.

You can assign sequence numbers at random to specific blocks or to all

blocks. You can call blocks assigned sequence numbers later by

designating their sequence number. Sequence numbers are necessary to

make program jumps and to specify a block for subprogram calls and

returns. For details on sequence number, see page 10-9.

program name it must be the first block entered in a program. This block

can be used to identify a program when reading from a tape (when

program name is selected as “automatic” from the device setup menu).

This is useful when many programs are placed together on a single tape.

An O-word can have up to 5 numeric characters following it.
