Method 1: Bit operator tests z/OS DFSORT Application Programming Guide SC23-6878-00 |
|
This method of bit logic testing allows you to test whether selected bits in a binary field are all on, all off, in a mixed on-off state, or in selected combinations of these states. While this method allows you to test many different possible bit combinations with a single operation, similar to the Test Under Mask (TM) machine instruction, it is less suited to determine if a field contains exactly one particular combination of on and off bits than Method 2 described later in this section. |
