Software migration from RSX to VMS: programming for transportability

Conference ·
OSTI ID:6697372

New users of VAX/VMS are often faced with migrating applications written for RSX11M into the VAX/VMS environment. Generally, applications written in a high level language can be migrated without too many changes, but the effort is complicated by the intrinsic differences in executive services between the two systems, and by differences in the behavior of the language compilers. The migration effort can be simplified by: (1) writing code using language features which work identically on both systems; (2) isolating operating system dependent features in system dependent subroutines; and (3) providing a set of executive service subroutine calls for use on both systems. These techniques have the advantage of producing code which is transportable between RSX and VMS systems.
