Structured System Variables^$GLOBAL as an argument to $ORDER returns the next or previous global name in collatingsequence to the global name you specify. If no such global name node exists in ^$GLOBAL,$ORDER returns a null string.The direction argument specifies whether to return the next or the previous global name. Ifyou do not provide a direction argument, Caché returns the next global name in collatingsequence to the one you specify. For further details, refer to the $ORDER function.The following subroutine searches the user's default namespace and stores the global namesin a local array named GLOBAL.GLOBSET NAME=""WRITE !,"The following globals are in ",$ZNSPACEFOR I=1:1 {SET NAME=$ORDER(^$GLOBAL(NAME))WRITE !,NAMEQUIT:NAME=""SET GLOBAL(I)=NAME}WRITE !,"All done"QUITAs an Argument to $QUERY^$GLOBAL as an argument to $QUERY returns the next global name in collating sequenceto the global name you specify. If no such global name exists as a node in ^$GLOBAL,$QUERY returns a null string.In the following example, three globals (^GBL1, ^GBL2 and ^GBL3) are present in theSAMPLES namespace.ZNSPACE "SAMPLES"SET (^GBL1,^GBL2,^GBL3)="TEST"ZNSPACE "USER"WRITE $QUERY(^$|"SAMPLES"|GLOBAL("^GBL1"))WRITE !,$QUERY(^$|"SAMPLES"|GLOBAL("^GBL2"))ZNSPACE "SAMPLES"KILL ^GBL1,^GBL2,^GBL3The first WRITE returns ^$|"SAMPLES"|GLOBAL("^GBL2")The second WRITE returns ^$|"SAMPLES"|GLOBAL("^GBL3")See Also• $DATA function• $ORDER function• $QUERY function504 Caché ObjectScript Reference
