Caché ObjectScript Reference - InterSystems Documentation

Structured System Variables$QUERY treats all global lock variable names, subscripted or unsubscripted, as characterstrings and retrieves them in string collating order. Therefore, $QUERY(^$LOCK("")) retrievethe first lock name in collating sequence order: either ^$LOCK("^A”) or a Caché-definedlock higher in the collating sequence. $QUERY(^$LOCK("^C")) retrieves the next lock namein collating sequence after the non-existent ^C: ^$LOCK("^D”).$QUERY(^$LOCK("^A(1,2)")) retrieve ^$LOCK("^A(1,2,3)”) which follows it in collationsequence.See Also• LOCK command• $DATA function• $ORDER function• $QUERY function• $ZNSPACE special variable• $ZUTIL(90,10) Test Whether a Namespace is Defined function• Configuring Namespaces in Caché System Administration Guide^$ROUTINEProvides routine information.^$|nspace|ROUTINE(routine_name)^$|nspace|R(routine_name)Parameters|nspace|or[nspace]routine_nameOptional — An extended global reference, either an explicitnamespace name or an implied namespace.
