FIELDSIZE()
 Determines the size of a field
------------------------------------------------------------------------------
 Syntax

     FIELDSIZE(<nField>) --> nLength

 Argument

     <nField>  Designates the number of the field to evaluate.

 Returns

     FIELDSIZE() returns a numeric value that corresponds to the field length
     of a valid field number.

 Description

     Use FIELDSIZE() to determine the length (or size) of data field of
     desired data types.  This determines the window width needed for output
     to appear without a line break, or the length needed for an input to
     automatically fit in the database.

 Note

     .  If there is an invalid data field number, the function returns
        a value of 0.

 Example

     Determine the total length of fields 3 to 5:

     nLength  :=  0
     FOR I = 3 TO 5
        nLength := nLength + FIELDSIZE()
     NEXT
