                int inDecPosition)
         throws xBaseJException,
                IOException

public method for creating a numeric field object. It is not associated with a database but can be when used with some DBF methods.

Parameters:

iName - the name of the field

iLength - the length of Field. range is 1 to 19 bytes

inDecPosition - the number of decimal positions range from 2 to 17 bytes. Relative to Length.

Throws:

xBaseJException - bad name, length or decimal positions specified

IOException - can not occur but defined for calling methods
