in the operand to 1.

double word D12.
December 2001
Syntax:
BS (BIT SET)
Operands:
B, W, D, K, X
Action:
With the BIT SET command you can set each bit in the accumulator to 1. The
corresponding bits are selected (addressed) by the content of the specified
operand or by a constant. As to the bit numbering, bit 0 = LSB and bit 31 =
MSB. For operand contents greater than 32, the TNC uses the operand value
modulo 32, i.e. the integral remainder of the result of the operand value
divided by 32.
Example:
Load double word D8 into the accumulator, set bit 0 of the accumulator to 1,
and save the result in double word D12.
Initial state:
Double word D8
= 3E 80 (hex)
Double word D12
= ?
