Thanks to all who replied so far. I received some questions on what POSIX is. 
POSIX is the attempt to unify software and interfaces to operating systems.
Most of the proprietary systems try to become 'POSIX compliant' which means
that all pieces of software with this label are expected to be (source)
code compatible and run without modifications. The User interface of POSIX
looks pretty much like UNIX. If you invoke POSIX on VMS you basically start 
a UNIX emulator (forgive me if this is a rather blunt interpretation). 

My specific question relates to the fact  that we are currently developing 
a software package and will put this into beta mid-august. The programs are
expected to deal with database update integration, i.e. you will be able 
to integrate an EMBL update into your existing database (eventually, an 
update database) in GCG or generic database format without the need to run 
a concatenation or other sort of purge/delete/replace action. 

As the software can basically run on all systems which currently support 
the GCG software, I considered to have the driving scripts written in shell 
or DCL commands. If all of you run POSIX on VMS, I would just distribute
the POSIX version. Code maintenance is much easier if the generic specialities
are not to be considered. 

I received a few replies which indicates attempts to run GCG under POSIX on 
VMS. Is this going to be a serious alternative?
