Anyone using CR9.x yet?
I'm playing with custom functions and it looks as if CR9.x still doesn't handle NULL values very well.
Using BASIC syntax I say:
if IsNull(str) then
and Crystal complains that ISNULL cannot be used in a custom function. I presume then that we will see the same functionality as in previous versions in that a null value will stop function evaluation cold - or am I missing something?
Sure would be nice to write a custom function in which I can pass in a value that might be NULL and test for it.
