The OS/360 I/O access methods are programming APIs on the OS/360 mainframe computer operating system, used by programmers to implement input/output operations on data sets (files). They are by convention referenced to with ...AM acronyms, standing for ... Access Method. They are now mainly used in OS/360's successor z/OS.
Including EXCP
While the Execute Channel Program (EXCP) macro, is included in this list, EXCP works with OPEN to allow callers to issue hardware specific channel commands to datasets on any device, storage or network, technically it is a dataset abstraction interface for higher level access methods. One variation of EXCP is XDAP, which is for storage, only, and is provided for reading and updating direct access storage records. XDAP cannot be used to add records to a dataset, but XDAP can be utilized with BSAM to effect record additions to such datasets.
