 PC Exchange (for VMS)   < PC Exchange (PCX) is a utility for copying files to and from? MS-DOS format diskettes under VMS, using an RX23 (3.5") or RX33 C (5.25") diskette drive.  For 3.5" diskettes, high-density disks can I be read or written; double-density disks are read-only. Only high-density   disks are supported on the RX33.     SYSTEM REQUIREMENTS  -------------------   , * VMS V5.0 or later (it may work under V4.x)  J * An RX33, RX33S, RX23, or RX23S diskette drive ("S" denotes SCSI variant)  B   Please read the AAAREADME.TOO file for information on bug fixes,8   known problems, and other version-related information.  # ==> RX26 support added  (Mars 1994)   ) * OpenVMS AXP 1.5 (vested version of PCX)    INSTALLING PCX --------------   To build the executable:  @ * If you have the object library, PCX.OLB, available, create the   executable with the command:  .     $ LINK/NOTRACE PCX.OLB/INCLUDE=PCX/LIBRARY  0   All required object files are in that library.  A * If you have the MACRO sources, execute the ASMBUILD.COM command C   procedure to assemble them and link the PCX executable.  You will A   probably have to first edit the file ACCESS.MAR and remove some A   extraneous semicolons from in between the continuation lines of 8   the big .LONG directive, close to the top of the file.  G * If you have the BLISS sources and the MMS description file available, -   use MMS to compile and link the executable.   D Once you have the PCX.EXE file, you can set up a DCL foreign command to run PCX:   "     $ pcx :== $disk:[directory]PCX   To build the help library:       $ RUNOFF PCX_HELP.RNH 6     $ LIBRARY/CREATE/HELP PCX_HELPLIB.HLB PCX_HELP.HLP  * To make the help library available to PCX:  4     $ DEFINE PCX_HELPLIB disk:[directory]PCX_HELPLIB  F If you install the help library in SYS$HELP, this step is unnecessary.     PRIVILEGES REQUIRED  -------------------   A * You may need VOLPRO privilege to use PCX.  PCX can be INSTALLed    with this privilege:  9     $ INSTALL CREATE disk:[directory]PCX/PRIVILEGE=VOLPRO   C   PCX turns off all image privileges at startup, and only activates    them when needed.      BEFORE YOU START ----------------  > Before using PCX, you must define the logical name PCX_DISK as@ the device name of the diskette drive.  One easy way to do that,@ while at the same time ensuring that no other process has access4 to the drive, is to use the ALLOCATE command, as in:  $     $ ALLOCATE/GENERIC RX23 PCX_DISK  > Using the /GENERIC qualifier also means you don't have to know= the physical device name of the drive (assuming you only have  one diskette drive available).     AVAILABLE COMMANDS ------------------  $ PCX provides the following commands:  E @                     executes a command file (default filetype .PCX) 1 ATTACH                attaches to another process , CREATE/DIRECTORY      creates a subdirectory7 DELETE                deletes a file or empty directory 2 DIRECTORY             displays a directory listing  EXIT                  leaves PCX& FORMAT                formats the disk# HELP                  displays help ; READ                  reads a file from the floppy onto VMS C SET PATH              sets current default directory path on floppy = SHOW PATH             displays current default directory path ) SPAWN                 spawns a subprocess C TYPE                  displays the contents of a file on the floppy 5 WRITE                 writes a VMS file on the floppy   G The help information explains the parameters and/or qualifiers for each  command.  P -------------------------------------------------------------------------------- CONTACTING THE AUTHOR   K Comments, suggestions, and questions about this software can be directed to - the author at one of the following addresses:    Mail:    Matthew Madison'          Engineering Computing Services )          Rensselaer Polytechnic Institute "          Troy, New York 12180-3590   Phone:  +1 518 276 2606   + E-Mail: (Internet)  madison@vms.ecs.rpi.edu 6         (BITNET)    MADISON@RPIECSVX or MADISON@RPIECS   COPYRIGHT NOTICE  I This software is COPYRIGHT  1989, 1990 RENSSELAER POLYTECHNIC INSTITUTE. M ALL RIGHTS RESERVED.
