We are looking into moving our DEC System 5500 users to a 6610 running
VMS 5.5 which I understand includes a POSIX kernel.  I would like to find out
what functionality the current UNIX users are going to lose (if any) running
under VMS 5.5 with the UNIX-like (or POSIX) shell.

The current production application is written in C, but I'm unsure of the
compatibility between an Ultrix system and the VMS environment. It seems
to me that the Ultrix ".exe" executable does not run in the VMS environment.

However, in the "POSIX" environment I believe the users are able to run
a UNIX-like shell w/o losing any of their curent capability. Please correct
me if I'm wrong.

What types of porting problems would the current application suffer with the 
move to VMS 5.5?

Any kind of heads up on such a move would be kindly received. Thanks.
