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
