Portability to UNIX

NBS V2.4 was the first version of NBS to be fully portable to UNIX - V2.2 onwards was written portably but had several deficiencies and bugs. The shared memory services of UNIX System V are sufficiently close to the VMS global section system services to require only a small amount of conditionally compiled code in the low-level ``create section'' and ``map section'' routines. There are however two limitations which may affect users planning to use the software on UNIX platforms.
