Sector7 are the world experts in software migration from VMS to Linux and Unix. Sector7 and SimCon have worked together for nearly 20 years on VMS migration projects and have successfully migrated many tens of millions of lines of VMS Fortran code.

Sector7's work in VMS migration has been of great importance in three areas:

VMS file handling: fpt will translate the file handling statements such as OPEN, READ and WRITE to standard Fortran syntax, and in doing so may insert calls to Sector7's VX/RMS libraries. This is essential for handling ISAM files and is important in situations where VMS file version control is used.
VMS library calls: VMS programs often make calls to the VMS system libraries. These libraries support, for example, inter-process communication, process timing, and form handling. Sector7's libraries support the emulation of many hundreds of these routines. fpt is used to fill in missing arguments and to modify some of the call-sites to achieve compatibility with modern Fortran.
Mixed Language Programs: Sector7 has considerable experience of the migration of C and COBOL from VMS, and also of Oracle Pro*FORTRAN. The collaboration between Sector7 and SimCon allows us to make a seamless migration of mixed language VMS programs.

IQS Solutions (Pty) Ltd.

SimCon has a long-standing and close relationship with IQS Solutions (Pty) Ltd. in Simon's Town, South Africa. IQS and SimCon collaborated on the migration of a major real-time radar control system, and IQS also has an important rôle in the Karoo Array Telescope (KAT) project.

David Flower Ltd.

SimCon works with David Flower Ltd. in research in the automatic analysis of physical units and dimensions in Fortran codes. The current activity is to instrument the Fortran code and to track the relationships between units and dimensions at run-time.

SimCon and David Flower Ltd. also work together in QA auditing of codes and migration of code from legacy systems.
