8.15.33 GREATER THAN (>)
1698
Syntax: > (GREATER 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 greater than the operand, the
condition is true and the control sets the logic accumulator to 1. If the word
accumulator is less 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 = ?
Function
Load the constant into the
word accumulator.
Check whether word
accumulator > operand; if
so, set logic accumulator
to 1.
Assign the result to
marker M500.
