Q:

Does ColdFusion throw error if function is not camelCase?

I am trying to investigate a bug and am not super familiar with ColdFusion.  There is a function call to isdefined(), which I believe should be isDefined().  What behavior does ColdFusion take if it runs into this kind of case discrepancy with a built-in function?  Does it return truthy? Does it skip the statement?
The traceback shows the error coming from a line within this <cfif isdefined(...)> statement, so I'm wondering if the incorrect casing could be affecting this.  Any thoughts?

A:

What Leeish said. Function calls are NOT case sensitive. See CF documentation, the correct usage is  IsDefined("variable_name")
If all else fails, post a bigger block of the code here and we'll see what we can do.
