Further information
1. This function is used to enumerate fields of a record type. The second parameter is used to store the current location in the list of fields; if this parameter is NULL, the first field of the record is returned. This function returns NULL if it is called with the reference to the last field. Otherwise, the returned value can be used as the input parameter ref to get the following field and so on.
2. The name, type and number are the returned field properties. The field number is used by the function XPRMgetfieldval to retrieve the value of the corresponding field in an object of this record type.
