printer or punch, of any spool files produced hy that device. With the SPOOL command, you spool your virtual device to the RSCS virtual
machine. You can also use the TRANSFER command to transfer files frem
your own virtual card reader.
The CP commands TAG, SPOOL, and TRANSFER are discussed in detail in

Program Development Using eMS You can use CMS to write, develop, update, and test: OS programs to execute either in the CMS environment (using OS simulation) or in an as virtual machine DOS programs to execute in either the CMS/DOS environment or in a DOS virtual machine CMS programs to execute in the CMS environment
The OS and DOS simulation capabilities of CMS allow you to develop OS and DOS programs interactively in a time-sharing environment. When your
programs are thoroughly tested, you can execute them in an as or DOS virtual machine under the control of VM/370. "Section 8. Developing OS Programs Under CMS" is for programmers who
use OS. It describes procedures and techniques for using CMS commands
that simulate OS functions.
"Section 9. Developing DOS Programs Under CMS" is for programmers who
use DOS. It describes procedures and techniques for using CMS/DOS commands to simulate DOS/VSE functions.
If you use VSAM and access method services in either a DOS or an OS environment, "Section 10. Using Access Method Services and VSAM in CMS and CMS/DOS" provides usage information for you. It describes how to
use CMS to manipulate VSAM disks and data sets. You can use the interactive facilities of CP and CMS to test and
debug programs directly at your terminal. "Section 11. How VM/370 Can
Help You Debug Your programs" shows examples of commands and debugging
techniques.

As you learn to use CMS, you may want to write programs for CMS applications. "Section 13. programming for the CMS Environment"
contains information for assembler language programmers: linkage
conventions, programming notes, and macro instructions you can use in CMS programs. Part 2. Program Development Using CES 125
