DCL symbols: see VMS::DCLsym
logical names: see the $ENV hash, which will give you any logical name
visible to your process. You can create process logicals by creating new
keys in this hash.
lexicals: no general solution - it depends on what the lexical actually
does:
RMS with bells and whistles: VMS::Stdio
f$setprv, f$privil: VMS::Priv
f$getjpi and kindred: VMS::Process
f$getqui: VMS::Queue
This doesn't exhaust the list by any means. The main omission I know of is
f$file_attributes. The Perl stat () function handles the portable portion
of this, but not the RMS-specific part.

Then you might (or might not) be interested in Text::CSV.

Michael Schwern's posting gets you off to a good start. I'd like to add
Time::Local (for when you don't need the full power of Date::Manip for
input conversion), and the POSIX subroutine strftime (for output
conversion), which knows about month names, days of week, and so forth.
Unfortunately, the documentation assumes you have access to the
strftime(3) man page, or a "C" library manual, or some such.
Caveat about Date::Manip - last I checked, it wouldn't work under VMS
without the TZ environment variable defined. Sullivan Beck has
thoughtfully provided in the Date::Manip docs a section titled "Should I
use Date::Manip", which is as good an introduction as any I know to the
embarassment of choice you have in this area.
