&SYSM_HSEV System Variable SymbolIn Figure 28 on page 278 the &SYSM_HSEV variable is updated immediately whenan MNOTE is issued with a higher severity.&SYSM_SEV System Variable SymbolUse &SYSM_SEV to get the highest MNOTE severity code for the macro mostrecently called directly from this level.The global-scope system variable symbol &SYSM_SEV is assigned a read-onlyvalue. The assembler assigns a value of zero when a macro is called and when amacro returns (MEND or MEXIT), the highest severity of all MNOTE assemblerinstructions executed in the called macro is used to update the variable.Notes:1. The value of the variable symbol is supplied as three numeric characters, not asan arithmetic (binary) value.2. The value of the type attribute of &SYSM_SEV (T'&SYSM_SEV) is always N.3. The value of the count attribute (K'&SYSM_SEV) is always 3.4. The value of &SYSM_SEV is unreliable if any MNOTE is incorrectly coded suchthat a diagnostic message is generated for the MNOTE statement. The cause ofthe diagnostic message must be corrected.In Figure 28 on page 278 the &SYSM_SEV variable has a value of 0 until INNERreturns. The OUTER macro uses &SYSM_SEV to determine which statements togenerate, and in this case issues an MNOTE to pass the severity back to the opencode.Chapter 7. How to specify macro definitions 277
