Example

CFScript

glob = createObject("component", "lib.cfmumps.global");
glob.open("myGlobal", ["key"]);
if(glob.defined().defined) {
  writeOutput("^myGlobal(""key"") is defined"); 
}

if(glob.defined().hasData) {
  writeOutput("^myGlobal(""key"") has data"); 
} 

if(glob.defined().hasSubscripts) {
  writeOutput("^myGlobal(""key"") has subscripts"); 
} 

glob.close();

CFML

<cfset glob.open("myGlobal", ["key"])>
<cfif glob.defined().defined>
^myGlobal("key") is defined<br>
</cfif>
<cfif glob.defined().hasData>
^myGlobal("key") has data<br>
</cfif>
<cfif glob.defined().hasSubscripts>
^myGlobal("key") has subscripts<br>
