1794 HEIDENHAIN Technical Manual iTNC 530 HSCI
9.8.32 LESS THAN (<)
Syntax:  < (LESS THAN)
Operands: B, W, D, K
Action:
This command sets off a direct transition from word to logical processing. 
Compare the content of the word accumulator with the content of the 
addressed operand. If the word accumulator is less than the operand, the 
condition is true and the iTNC sets the logic accumulator to 1. If the word 
accumulator is greater than or equal to the operand, it sets the logic 
accumulator to 0. The comparison takes place over the number of bits in the 
operand: 
where B = 8 bits, W = 16 bits, and D = K = 32 bits.
Example:
Compare a constant with the content of double word D8, and assign the result 
to marker M500. 
Initial state: 
Constant  = 16 000 (dec) 
Double word  D8  = 15 000 (dec) 
Marker M500 = ?

not, set logic accumulator 
to 0.
