Segment Control Block Module 197,23,03 Block 1234 S3=7 but Module 197,23,03 Block 1233 already has that priority

Another Segment Control Block in this module specifies the same priority. (The two blocks have the same value of S3.)

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.

So it does not explicitly prohibit two segments with the same priority, but neither does it say exactly what happens when two have the same priority.

This message is likely to show an error in the system configuration. It should be reviewed. The issue raised may be in unused logic or graphics, or have other realities that make it a non-issue.
