OUT
The AND LOAD instruction can be used repeatedly. In programming method
(2) above, however, the number of AND LOAD instructions becomes one less
than the number of LOAD and LOAD NOT instructions before that.
In method (2), make sure that the total number of LOAD and LOAD NOT
instructions before AND LOAD is not more than eight. To use nine or more,
program using method (1). If there are nine or more with method (2), then a
program error will occur during the program check by the CX-Programmer.
