The pathname specification may be of the form: VOL.DIR.DIRl:FILES. If this pathname form is
specified, received data is routed to consecutive files, beginning with VOL.DIR.DIRI.FILEOO and
ending with VOL.DIR.DIRl.FILE99 (or some value less than 99 if the capacity of the device is
exceeded), and then continues to the next entry on the queue. The maximum length of FILE in
pathnames of this form is six characters.
Binary Data Receptions. In a 990 to 990 communication environment, the Emulator can receive
binary data. Binary is specified using a # (pound sign). The pound sign precedes the receive
pathname specified by the RPR or RPU command. The pound sign(#) specifies to the Emulator that
the file should not be translated.
Binary data is automatically transmitted with transparency on. Binary data must be transmitted in
fixed length records or single record blocks. The transmitting and receiving stations should agree on
a record length.
Received binary files should not be directed to the printer unless binary or nontranslated data is
expected. Since these files are not being translated, printing results may be unpredictable.
The DXIO program files must be transferred as binary files. The transmitting and receiving stations
must specify a record length of 288 bytes. To prepare the program file for the transfer, execute a
Backup Directory (BD) specifying the complete pathname of the program file to
be
transferred. The
Backup Directory creates a sequential file that can
be
transmitted. To transmit the file, precede the
pathname with a pound sign (#)(specifying do not translate) and use this pathname in the Sor SS
command. The receiving DX 10 must do a Restore Directory (RD) before using the file.
4.!.4.1 Receive Printer Data Command (RPR). Use RPR command to specify the destination
pathname (device or file) for each received data file with line printer device selection.

The vertical format control characters are deleted when the destination is a data file, magnetic
tape, or cassette (unless VFC=ON is specified). When the destination is a VDT or TTY
terminal, the output is single spaced. The vertical format control characters are translated to
software forms control formatting for files directed to the line printer.
Examples:
Receive print file in pathname .DIR.FILE.
General format:
COMMAND: RPR
PATHNAME: .DIR.FILE
Receive binary print file in pathname .DIR.FILE.
