exec-name(task-name) ALR3 buffer is missing/invalid
Error message issued by functions ALERTRTN (VNCRXF31) and ALERTRSL (VNCRXF32).
If the ALR3 alert buffer is “missing,” then the exec that called the function was not called from an alert rule, so there is no alert buffer to process. This is a user error.
If the ALR3 alert buffer is invalid, the storage class ID in the buffer is not the expected ALR3.
This is an internal logic error.
