Arguments
If the newValue argument is not provided, value() will return the existing value.
| Name | Type | Required | Description |
|---|---|---|---|
| newValue | string | No | The value to be set |
Return Value

Example
CFML
<!--- this is equivalent to the following MUMPS code:
set ^people(1,"name")="John Willis"
write "Name: ",^people(1,name),!
--->
<cfset glob = new lib.cfmumps.Global("people", [1, "name"])>
<cfset glob.value("John Willis")>
<cfoutput>
Name: #glob.value()#<br>
</cfoutput>
