     Character    Data Type
     ------------------------------------------------------------------------
     C            Character string
     N            Numeric
     D            Date
     L            Logical
     M            MEMO

 Description

     FIELDTYPE() operates in a similar fashion to the CA-Clipper TYPE()
     function.  With TYPE(), you must always know only the name of the data
     field.  However, FIELDTYPE() requires that you only know the data field,
     not its name.  Use the function to confirm data types for data fields
     when a program is working with different databases that have different
     field names.

 Note

     .  If there are  invalid data field numbers, the function returns
        a null string.

 Example

     Data type for field number 5:

     IF FIELDTYPE(5) = "C"
        ? "Field No. 5 is a character field!"
     ENDIF
