^$G[LOBAL] ( gvnexpr )
gvnexpr | ::= | expr | V | ^ name |
^$Global provides information about the existence and characteristics of global variables.
If and only if a global variable identified by gvnexpr exists, ^$Global( gvnexpr ) is defined ($Data returns a non-zero value); all non-empty string values are reserved for future extensions to the standard. Global variable characteristic information is stored beneath the ^$Global( gvnexpr ) node:
^$Global( gvnexpr , expr V "CHARACTER") = charsetexpr
This node identifies the Character Set Profile of the specified global variable. When the first node in a global variable is created, and the node ^$Global( gvnexpr , "CHARACTER" ) has a $Data value of zero, the value assigned is that of ^$Job( $Job, "CHARACTER" ). The result of killing a gvn does not alter the characteristics stored in ^$Global for that gvn.
