A while back I posted an article asking for a utility to read and write
MSDOS-format floppies on a VMS system.  Since I got no responses, I
broke down and wrote one myself.  I have just posted PC Exchange (PCX)
to vmsnet.sources, and I have placed it on vms.ecs.rpi.edu [128.113.5.15]
and vms2.ecs.rpi.edu [128.113.5.14] for access via anonymous FTP or
through E-mail to Fileserv@vms.ecs.rpi.edu.

Since this if version 1.0 of the program, I expect that there will be
at least a few bugs in there that I haven't caught.  Also, although
it should work with the RX23, RX23S, RX33, and RX33S drives, I have
only been able to test it out with the RX23S in my VAXstation 3100/M38.
(BTW, the S denotes SCSI interconnect, as opposed to ST506.)  I would
be interested in hearing from people who try to use PCX with other types
of drives.

You can read double- or high-density diskettes.  Only high-density
diskettes are supported when writing or formatting (a VMS or hardware
restriction, I guess).  It fully supports MSDOS directory structures.
Documentation is a bit thin, but there is a help file.  Sources
are available in both BLISS and MACRO (as generated by the BLISS
compiler).  The vmsnet.sources posting only includes the MACRO
source, to save space.

Later,
Matt
