PCS
The Parameter and Communication Subsystems
Application programs often need to obtain parameter values from a variety of sources and to communicate with other programs. The Parameter and Communication Subsystems (PCS) are a set of closely-related subroutine libraries which provide these facilities for many Starlink applications and the associated user-interfaces.
The PCS libraries will not generally be called directly by application programs, but form a basic part of the Starlink Software Environment which is described in Starlink Guide SG/4. Additional notes on using it under Unix are given in Starlink User Note SUN/144.
