code

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only

   this argument. The valid function codes are as follows:

   Function Code    Description

   EDT$K_OPEN_IN_   Open the work file for both input and output.
   OUT              Neither the record nor recordno argument is
                    used.
   EDT$K_GET        Read a record. The recordno argument is the
                    number of the record to be read. The record
                    argument gives the location where the record is
                    to be stored.
   EDT$K_PUT        Write a record. The recordno argument is the
                    number of the record to be written. The record
                    argument tells the location of the record to be
                    written.
   EDT$K_CLOSE_DEL  Close the work file. After a successful close,
                    the file is deleted. Neither the record nor
                    recordno argument is used.

   access:       read only
