Hardware Devices Supported CMS/DOS routines can read real DOS disks containing DOS data files and DOS private and system libraries. This read support is limited to the
following disks supported byDOS/VS: • IBft 2314 Direct Access Storage Facility • IBM 2319 Disk Storage • IBM 3330 Disk Storage, Models 1 and 2 • IBM 3330 Disk Storage, Model 11 • IBM 3340 Direct Access storage Facility • IBft 3344 Direct Access storage • IBM 3350 Direct Access storage
Also, underCMS/DOS you can write VSAM data sets. VSAM data sets can
only be written to disks that are supported byDOS/VS. The following devices, which are supported by BOS/VS, are not
supported byCMS/DOS: • Card Readers: 1442, 2560P, 2560S# 2596, 3504, 5425P, and 5425S • Printers: 2560P, 2560S, 3203 Models 1 and 2, 3525, 5203, 5425P, and 5425S • Disks: 2311
Also,CMS uses the CP spooling facilities and does not support
dedicated unit record devices. EachCMS virtual machine supports only
one virtual console, one reader, one punch, one printer, four tapes, and
ten disks. Programs that are executed ineMS/DOS are limited to the
number of devices supported byCMS. eMS Support of DOS/VS Functions
In addition to theCMS SET command used to invoke the CMS/DeS environment, there are a number of CMS/DOS commands and CMS commands
with specialCMS/DOS operands that provide CMS support of the following DOS/VS functions: • Assignment of logical units to particular physical devices. • Associating DOS files with particular logical units. • DOS/VS Librarian Services. • Compilation and testing of DOS/VS COBOL and Des PL/I programs. • Execution of DOS/VS COBOL and DOS PL/I programs. Figure 32 summarizes these new commands and the new operands fer
existing commands.A detailed description and command format can be
found in the!ttLl1Q Part 3. Conversational Monitor System (CMS) 285
