TSTQ tests executive block [CHECK 156]

TSTQ Module 1,01,02 Block 1001 tests quality on executive block Module 1,01,02 Block 3, which does not have quality

The TSTQ block inputs must have quality. If they do not, the test is useless. However, testing quality of executive constant blocks appears to be a common way of disabling unneeded logic.

Testing constants is generally visible and often intentional, acting as a simple place holder in multipurpose logic.

Function codes that have quality or propagate the quality of their input are listed at Function codes with quality.
