I think you only have ;-1 and ;0 which are special.
Can't speak for RSX's problems, but for VMS none of this is true.
Wow. I apologize. I thought I had that under control... :-)
I wonder if VMS have changed along the way, or if it has always been like that...?
In RSX it is as I described, however...

Actually, in VMS (as well as in RSX), ;-1 means the oldest version available.
Around here is where VMS differs from TOPS-20.
;0 also have different meanings on TOPS-20 compared to VMS.
On VMS, ;0 means the most recent version if you open a file for reading. But if you try to create a file, ;0 means one higher than what exist right now.
In TOPS-20, unless my memory fails me, ;0 will overwrite the most recent version that do exist.
The ;-0, ;-1, ;-2, ;-3 and so on to refer to older versions is how I think TOPS-20 did it. I don't remember that there is a way of specifying something like that in VMS. I think you only have ;-1 and ;0 which are special. But I might be remembering wrong from playing too much with RSX. :-)

One is starting to hope that PHP gets _some_ of the filespec stuff
right. :)
But, while I'm willing to believe (at least until I have time to study
it a bit more) that it's PHP which looks to see if it owns the requested
extension, I'm reluctant to believe that Apache hands over full pathname
processing. That should reduce the size of the problem space a little.
I wonder if case matters...
The rule might better read:
RewriteRule (.*\.[Pp][Hh][Pp])([;.][0-9-]*)(.*) $1$3

G.
As in "FOO.TXT;" ?
That certainly *used* to be a valid filename, back in V4/V5 days anyway,

And, FWIW, it's also legal to use angle brackets in VMS path
specifications (e.g. "DISK:<DIR.DIR.DIR>FOO.TXT"). Both the use of angle
brackets and using a second "." in place of the semicolon (e.g. "FOO.TXT.1")
were put into VMS long ago as an aid to ex-TOPS20 users.

Any other separator legal for version numbers? Am I missing anything
else?
Surely I'm showing my ignorance of both VMS and Apache, but does your
regex handle a version # with no digits at all? As in "FOO.TXT;" ?
That certainly *used* to be a valid filename, back in V4/V5 days anyway,
just want to make sure it's covered.

Both. Since we're talking about legal filenames in VMS, it means that CSWS_PHP must understand them as well, or else they are just easy ways of getting around your rewrite rules.

Indeed. You can also use <> instead of [] as directory brackets.
All because of confusion within DEC at the time when they tried to
decide on a standard for all DEC OSes.
(Because of this confusion, TOPS-20 changed it's syntax to be <> and .,
but then VMS reverted the decision, but in the end they had to allow
both variants, to keep something like compatibility between VMS and
TOPS-20. RSX also allows the same.)

Oh god, that brings back some bad memories, "Where the **** is that squiggly thing on this stupid Finnish keyboard? I am never using these stupid umlauts when I grow up, damn it" = me at around 12 years of age.
And here we are, 20 years later, I can barely string together a coherent written sentence in my native tongue. I blame ASCII.

The reason for avoiding [] is that those are "national characters" --
they might be letters with umlauts or stuff like that, in the ancient
days of non-English 7-bit character sets. Latin-1 obsoleted that
notion. But until that happened, there was an internal DEC directive
to avoid those code points... []{}\_|# and perhaps even $...
A few people paid attention, most (like RSTS) just ignored it.
Indeed. But after a while I got used to reading DB0: 120,114 :-)
