>I'm glad you asked, it prompted me to add ISARRAY to my own code libary like this:

FUNCTION ISARRAY( tcVar)
>RETURN TYPE("tcVar[1]") <> "U"

For ISARRAY() to work you need to pass the variable by reference. For example:

myVar = 3   && a variable
>dimension myArray[1]    && an array
>myArray[1] = 3
>?ISARRAY( @myVar)   && returns .F.
>?ISARRAY( @myArray) && returns .T.

Hi Rick,

You may want to add this function to UT FAQ section.
