5-18-8 MOVE BIT – MOVB(82)

The following example shows how to use COLL(81) to create a stack between

DM 0001 and DM 0005. DM 0000 acts as the stack pointer.

When IR 00000 goes from OFF to ON, COLL(81) copies the content of

DM 0005 (DM 0000 + 5) to IR 001. The content of the stack pointer (DM 0000)

is then decremented by one.

The offset or stack length in the control word is not BCD.

Indirectly addressed EM/DM word is non-existent.

(Content of *EM/*DM word is not BCD, or the EM/DM area boundary

has been exceeded.)

During stack operation, the value of the stack pointer exceeds the

length of the stack; an attempt was made to write to a word beyond

the end of the stack.

ON when the content of S is zero; otherwise OFF.

Ladder Symbols

The rightmost two digits and the leftmost two digits of Bi must each be

between 00 and 15.

DM 6144 to DM 6655 cannot be used for Bi or D.
