Segment control block bad priority [ERROR 300]

Segment Control Block Module 197,23,03 Block 1234 priority S3=314 is not in the range 0..255

Segment priority S3 must be in the range 0–255.

The Function Code User Manual says:

S3 – SPRI

(Segment priority) Assigns execution priorities to up to eight active segments. An active segment is one that is ready to run or is running. If two or more segments are active, the processor will run the highest priority segment. Segment priorities should be selected from zero to seven with zero being the lowest priority segment.

In spite of this recommendation, segment priorities up to 255 are permitted.
