Caché ObjectScript Reference - InterSystems Documentation

System and Other FunctionsThus, if you issue $ZUTIL(5,current) and then issue OPEN for a sequential file withoutspecifying a namespace, the operating system either:• Finds the file in current• Creates the file in current if the file does not existIf you issue $ZUTIL(5,current) in a subroutine, the original routine finishes; however,routines called are taken from the new namespace, current. When you halt from Caché, yournamespace reverts to the one you were in when you entered Caché.If you incorporate $ZUTIL(5,current) into a library routine from the system manager'snamespace (%SYS), you give all programmers access to all namespaces regardless of theirUIC or privilege level.When using $ZUTIL(5) to change the current namespace, Caché clears the global vectors.However, when issuing a $ZUTIL(5,current), where current is the current namespace (inother words, not changing the namespace), Caché does not clear global vectors. If you wishto clear global vectors without changing the current namespace, use $ZUTIL(69,43,1) beforecalling $ZUTIL(5).If you wish to have a process reference the routines in another namespace, without changingthe current namespace, use $ZUTIL(20) or $ZUTIL(39).See Also• ZNSPACE command• $ZUTIL(20) Specify namespace to search for routines function• $ZUTIL(39) Specify namespace to search for % routines function• $ZUTIL(68,43) Disable or Enable Clearing of Global Vectors for the Current Processfunction• $ZUTIL(69,43) Disable or Enable Clearing of Global Vectors System-wide function• $ZUTIL(90,10) Test Whether a Namespace is Defined function• $ZNSPACE special variable• Configuring Namespaces in Caché System Administration Guide568 Caché ObjectScript Reference
