CHARON-VAX application note
AN-006 Sharing disk container files with other VMS systems
Author: Hunter Goatley

The biggest issue for Hobbyist users of CHARON-VAX is the transfer of files into and out of
the CHARON-VAX VMS system. Methods of doing so include transference via Kermit or
some other file transfer protocol, or via a floppy drive and the use of MGPCX (see
CHARON-VAX application note AN-007).
If you have access to other VMS systems, you can also transfer large amounts of data inside a
VMS container file. The ODS-2 container files used by CHARON-VAX are compatible with
the container files used by virtual disk drivers that run under VMS, including Glen Everhart’s
VDDRIVER and LD, the loadable disk driver found on the VMS Freeware CD.
To transfer a VMS directory structure easily, simply create a virtual disk on VMS using the
software of your choice. Once the virtual disk has been populated, simply dismount the disk,
and then use FTP to transfer the container file to your PC running Windows or Linux (be sure
the file is transferred in BINARY mode).
Once the file has been transferred to the PC, you can specify the name of the file in the
CHARON-VAX initialization file and then access it from VMS running under CHARONVAX just as you would a disk created by the MKDISK utility.
Obviously, the reverse is true, too. Any CHARON-VAX disk image can be FTPed to a VMS
system and accessed via the virtual disk driver.
Naturally, large container files can take quite a while to transfer between systems, but
transferring container files back and forth can be a quite painless method of transferring data
in and out of CHARON-VAX.
