IsEmpty() and Local Vars.

Hello all:

Does anyone see any problems w/ the following :

IsEmpty ($variable)

It seems to work just fine but the documentation for this function under 'format' says:

IsEmpty (field)

So I was just wondering if putting a local variable in this function instead of a field is a good idea.

Sincerely,

Dom

... but some lines down, it says:

Parameters

field - any field name, text expression, or numeric expression

So yes, that is correct and these ones are all true:

IsEmpty ( "" )

IsEmpty ( Trim ( " " ) )

IsEmpty ( Filter ( "abc"; "ABC" ) )
