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.
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.

True in VMS, not in RSX. That's a small feature for cultural
compatibility with TOPS-20...

Just to clarify, are we now talking about the flaw in CSWS_PHP or just general syntax for VMS filenames? Or both?

For the record, both [] and <> will work on TOPS-20 for directory names.
Brackets [] are naturally preferable because they don't require a shift,
which is much more comfortable when typing quickly.

(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.)

This regex is going to be like 800 chars, right?
Probably. :-)
The syntax for the filename is a little tricky, unfortunately.
And with ODS-5, it is probably even worse...

And zero (which in fact is the default). :-)
