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 = createObject("component", "lib.cfmumps.global")>
<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>
