    The following examples should clarify the use of 'set data
type' transactions.

1.        USER                                             SERVER
          ----                                             ------
                    Set data type '02' (Network ASCII)
                    ------------------------------------->
                    Store File X
                    ------------------------------------->
                    File X (in Network ASCII)
                    ------------------------------------->
                    End of File
                    ------------------------------------->
                    Acknowledge
                    <-------------------------------------

                    Retrieve File X
                    ------------------------------------->
                    File X in Network ASCII
                    <-------------------------------------
                    End of File
                    <-------------------------------------

2.        USER                                             SERVER
          ----                                             ------
                    Set data type'03' (EBCDIC)
                    ------------------------------------->
                    Retrieve File Y
                    ------------------------------------->
                    Set data type '00' ("bit-stream")
                    <-------------------------------------
                    File Y as stored (no conversion)
                    <-------------------------------------
                    End of File
                    <-------------------------------------

                    Set data type '02' (Network ASCII)
                    ------------------------------------->
                    Retrieve File Z
                    ------------------------------------->
                    File Z in Network ASCII
                    <-------------------------------------
                    End of File
                    <-------------------------------------
