Hmm, I should have checked the Help file :)

>I don't think your TYPE check is correct. There is no 'M' for types. You better check for not being 'U' (undefined).

>If you read the VFP help file, you will see that there is an 'M' type. This is from that topic:
>
>Return value Data type
>A Array (only returned when the optional 1 parameter is included)
>C Character, Varchar, Varchar (Binary)
> If the optional 1 parameter is included, a return value of C indicates that the data type is a collection.
>D Date
>G General
>L Logical
>M Memo
>N Numeric, Float, Double, or Integer
>O Object
>Q Varbinary
>S Screen
> Note
> The Screen type is created when using the SAVE SCREEN command. For more information, see SAVE SCREEN Command.
>T DateTime
>U Undefined type of expression or cannot evaluate expression.
> If the optional 1 parameter is included, a return value of U indicates that the data type is not an array.
>W Blob
>Y Currency
