Running Programs in the Foreground

Two TSO/E commands run a program in the foreground:

RUN command - If your installation has certain program products, you need only issue the RUN command and the program products automatically compile, link-edit, load, and execute the program. For information about the RUN command, see z/OS TSO/E Programming Guide and z/OS TSO/E Command Reference.
CALL command - If a program has been previously prepared and is ready to run, you need only issue the CALL command to load and execute it.
