There's no built-in function to do this, but you could do something like this:

function IsNumeric(string itemName)
    IsNumeric = ( getvalue(itemName) <> default );
end;

This would work in most cases, though if the item was numeric and value happened to be default, then it would falsely report as being alpha.

OK Martin,
thank you !
