Parallels between the MVS environment and the shell environment

z/OS UNIX System Services User's Guide
SA23-2279-00

Figure 1 indicates how basic programming tasks are performed in the MVS™ environment and in the shell environment.

An interactive user who uses the OMVS command to access the shell can switch back and forth between the shell and TSO/E, the interactive interface to MVS.
  • Programmers whose primary interactive computing environment is a UNIX or AIX® workstation find the shell programming environment familiar.
  • Programmers whose primary interactive computing environment is TSO/E and ISPF can do much of their work in that environment.
Figure 1. Working interactively in the MVS and shell environments
It is possible to work interactively between MVS and the shell environment. For example, in the MVS environment, the ISPF editor is used while in the shell environment, the vi and ed shell commands are used.
