Developing VSE Programs under CMS

CMS simulates many functions of the Disk Operating System (DOS) VSE so you can use the interactive facilities of z/VM to develop and execute your VSE programs in a VSE virtual machine or in a batch facility virtual machine. CMS simulation of DOS is not necessarily the same as the current support of DOS. However, you can use CMS to create, compile, test, execute, and debug VSE programs written in the Assembler, DOS/VS COBOL, DOS PL/I, DOS/VS RPG-II programming languages.
