UDFs have access to the local scope. So consider this:
<cfscript>
x = 1;
function foo() {
writeOutput(x);
x = x + 1;
writeOutput(x);
}
</cfscript>
<cfoutput>#foo()#</cfoutput>
This will output 12 and will set x to 2. I could have also done
variables.x = variables + 1.
If you do NOT want to write to the local scope, you must use argumenets
or var scoped vars:
function doIt(x,y) {
var z = 1;
}
In this example, x and y refer to arguments passed to the UDF and will
NOT overwrite any existing x or y var. Z is also local.
