The input specifications describe the record that the RPG program receives from the display or ICF device. The WORKSTN file name must be specified in positions 7 through 16. Input fields must be located in the input record in the same sequence as defined in the DDS; however, the field names do not have to be the same. The field location entries refer to the location of the fields in the input record.
A record identifying indicator should be assigned to each record in the file to identify the record that has been read from the WORKSTN file. A hidden field with a default value can be specified in the DDS for the record identification code.
