Bhaskar,
As long as you have the hood up, I'd like to ask about GT.M with respect to
"linking". As you know, the recent conversations about open source licensing
touched on the issue of static versus dynamic linking. This seems to be the
line that separates "contaminated" from "uncontaminated" code. (Excuse the
euphemisms.) So, what I would like is your explanation of the linking that
exists between routines from two different packages running in a single user's
job space. For example, if you are running FOIA VistA and an add-on accounting
package together, how might they be linked? If there are multiple answers,
that's OK. I think this is relevant -- because, based on my understanding of
what is going on, I think we may need to redefine certain terms in an M context
because I'm not sure that the industry standard terms apply.

There are some differences down in the detail level, mostly as a result
of differences between hardware architectures, operating systems, as
well as what development found funding and what did not.
There are differences between GT.M on Alpha/VMS and GT.M on UNIX/Linux:
the underlying OS platforms are different enough that we have different
manuals for them - although the manuals are generated from a common
source with conditional text. The UNIX implementations support
identical implementations of the M language, but here are some examples
of the differences:
* Some platforms support a "Direct IO" flag which turns on the
O_DIRECT setting for journal IO, which can either speed things
up or slow things down depending on the IO subsystem.
* GT.M on Sun SPARC Solaris supports Sun RPC call-ins. The others
don't.
* The GT.M compiler on AIX, HP-UX and Tru64 UNIX creates object
files in a format that can be incorporated into .so shared
libraries. The GT.M compiler on Linux and Solaris does not.
* There may be differences in the ability to pass parameters in
registers when calling between M and C on the different
platforms, but I can't remember right now.
* A GT.M process on AIX can have fewer database files open at one
time than on other platforms (the limit is something like 9
caused by fact that each shared memory segment uses a segment
register).
