Self-extracting kits for OpenVMS: one .BCK file becomes one .EXE program.

Version	X-02-00ECO01
Status	Maintained
Platforms	OpenVMS Alpha and I64
Licence	Apache License 2.0
For whom	Those who move BACKUP kits between OpenVMS systems by FTP, mail or USB.

What it is

A .BCK file loses its record attributes when passed through FTP, mail or a web server. A Fixed 512 .EXE passes intact, and the saveset attributes travel inside. The data is compressed by the standard DCX routines; a CRC-32 is checked before writing and a second CRC-32 after unpacking. A kit can be checked on Linux too (tools/yadcx_check.py).

Why

Reliable delivery of software kits to any OpenVMS system with no extra programs.
