If nspace does notexist, Caché generates a error.nspace can be an explicit namespace or an implied namespace.Caché maintains the name of the current namespace in the $ZNSPACE special variable.You can change the current namespace by using the ZNSPACE command, the $ZUTIL(5)function, the %CD utility, or by setting the $ZNSPACE special variable. Use of ZNSPACEor %CD is preferable, because these provide more extensive error checking.You can determine the current namespace from the $ZNSPACE special variable or the$ZUTIL(5) function. You can determine whether an explicit namespace is defined on yoursystem using the $ZUTIL(90,10) function.On UNIX and OpenVMS systems, you can set the system-wide default namespace using the$ZUTIL(90,4) function. Calling this function has no effect on Windows systems. For Windowssystems, the system-wide default namespace can be set using a command-line start-up option.For information on creating and modifying namespaces, and mapping databases, routines,and globals to a namespace, see Configuring Namespaces in Caché System AdministrationGuide.ArgumentspcOptional — An optional postconditional expression. Caché executes the command if thepostconditional expression is true (evaluates to a non-zero numeric value). Caché does notCaché ObjectScript Reference 397
