This chapter contains Programming Interface Information.

Automatic class selection (ACS) routines are for automatically assigning management classes to files and directories. The ACS routines are written in the ACS language, a high-level programming language. After writing the routines, you must translate them into an object form that DFSMS/VM understands (see Translate ACS Routines). A successful translation places the ACS object in a specified source configuration file. After you activate the configuration contained in that source configuration file, the ACS routine governs storage management.

This chapter contains four topics. The first section describes the ACS language constants. The second section describes read/write variables. The third section describes read-only variables that the ACS routine uses for comparison operations. The fourth section describes the ACS language statements. For samples of the ACS language statements used in ACS routines, see Sample ACS Routines.
