Yeah, ISO has been around a long time now. It is still a perfectly
valid format supported on most systems.
But the VAX/VMS "ISO" is a misnomer. It is not in ISO format, it is
in Files-11 ODS-2 format. That happens to be even older, and still
completely supported by VMS. The host that makes it doesn't need to
know jack about it, it just needs to copy the blocks to the CD.
Copying the misnamed ISO file to CD is a synch using the Disk Utility
on a Mac. There should be some tool for Windows, which, like Mac
Disk Utility, does not care what is inside the file but just copies
the blocks to the CD.
Alternatively, dd on Linux or UNIX will accomplish the same thing.
