&SYSM_HSEV System Variable Symbol

Use &SYSM_HSEV to get the highest MNOTE severity so far for the assembly.

The global-scope system variable symbol &SYSM_HSEV is assigned a read-only value. The assembler compares this value with the severity of MNOTE assembler instructions as they are encountered and, if lower, updates it with the higher value.

Notes:

The value of the variable symbol is supplied as three numeric characters, not as an arithmetic (binary) value.
The value of the type attribute of &SYSM_SEV (T'&SYSM_SEV) is always N.
The value of the count attribute (K'&SYSM_SEV) is always 3.
The value of &SYSM_HSEV is unreliable if any MNOTE is incorrectly coded such that a diagnostic message is generated for the MNOTE statement. The cause of the diagnostic message must be corrected.

In Figure 1 the &SYSM_HSEV variable is updated immediately when an MNOTE is issued with a higher severity.
