Well, okay, but I never had a use for this that I can think of...
<cfscript>
function IsList(list) {
if (arguments[2] EQ "") arguments[2] = ",";
if (ListLen(arguments.list,arguments[2]) GT 1) return TRUE;
return FALSE;
}
</cfscript>
<cfset variables.A = "Apple">
<cfset variables.B = "Apple,Orange,Lemon">
<cfoutput>
<p>A is a list: #IsList(variables.A)#</p>
<p>B is a list: #IsList(variables.B)#</p>
</cfoutput>
By the way, you can pass in delimiters just like you can with regular list
functions, but the default delimiter is (shock) a comma, so you don't have
to pass one in that case.
