Compare the contents of two data registers. The first data register (Parameter #1) is tested by comparing it
against the data value in the second data register (Parameter #2). The result is a condition code that can be used
for program conditional processing (see QJ command). For Example, if the first data register is greater than the
second the “greater than” flag is set and the QJGx command can be used to create a conditional jump.
