As I read your message I realize that perhaps I need to refactor this function into a method of application object. I have always thought that use of application object should be done vary sparingly since it adds to the application memory footprint. But this particular function is just 2 lines as the following:

FUNCTION GetFieldCaption
LPARAMETERS nFieldId
RETURN (gaFieldCaption[nFieldId])

And the array gaFieldCaption used by the function is PUBLIC so making it into the property of the application object will not increase the application memory use.

Thank you for your input.

>TYPE("Expression()") is the best way to do this. Type evaluates whatever expression you feed it and then returns the type value. I use this all the time and it definitely works, but you have to understand that when you call TYPE("SomeFunction()") you are actually executing SomeFunction() just in order to get the type which may or may not be a problem.
