To be honest, I think that has always been true. I believe that RSI
has never made any guarantees that compiled DLMs would work across
release versions.

I never new there were 32bit and 64bit versions of IDL.
It's probably safest to assume that there are other changes to the way IDL
variables are stored internally, and recompiling all C/FORTRAN etc. code
which deals with IDL variables would be prudent. It does mean that if you
want to support multiple versions of IDL you have to have multiple versions
of all your external code, though.

Yes:
"Maximum String Length Limit Increased for 32-Bit IDL
Prior to IDL 5.5, 32-bit IDL had a maximum string length limit of 64K (65534
characters) while 64-bit IDL allowed strings to be up to 2.1GB (2147483647
characters) in length. With IDL 5.5, this limit has been raised to 2.1GB for
both types
of IDL."
Though AFAIK it doesn't point out the implications of this for
call_external.

As an corollary to a previous thread on passing strings to call_external in
5.5, is the fact that the string length is changed to 32bit mentioned in
the "What's New"?

As soon as the lovely X11 port to the Mac is completed... and if I
survive the shock from seeing it...

Very shabby indeed.
For those of you who use Emacs and IDLWAVE, I'm putting the finishing
touches on an IDL v5.5 update to the online help, which incorporates
most of the updates to 5.5 as listed in "What's New". You'll get all
the correct keyword completion, uniform access to the new routines added
(like CPU ;), and even modified and new keyword/argument documentation
"in-place" in the online help. It's a text-based help system directly
converted from IDL's PDF help files, but it's *very* fast and insanely
convenient.
For those of you who don't use Emacs and IDLWAVE... maybe now's the time
to consider it.
For those of you who think Emacs is that old video format that lost out
to VHS in the 80's, nothing to see here.
