Planning Considerations for CMS Additionally, you can invoke the CP commands available to all virtual
machines underVM/370 directly from CMS. Using these CP commands, you
can send messages to the operator or to other users, dynamically change
your virtual machine's configuration, and invoke spooling facilities.
InCMS, the facilities of CP and CMS together appear as those of a
single integrated system.
To useCMS, you must first gain access to a virtual machine via the CP LOGON command, and IPL CMS. Then you can enter commands or data from
the remote terminal (virtual operator's console). Each command, upon
completion, returns control to you. For information about how to useCMS and for a description of all CMS commands, see the ang and the VM/37Q. eMS Program language Facilities The languages available under CMS include: S/370 Assembler VS BASIC PL/T as FORTRAN IV OS/VS COBOL DOS PL/I Optimizer DOS/VS COBOL VS APL The assembler is distributed with VM/370. The language compilers
that are program products must be ordered separately. For a complete
