If you invoked the debugger with the DCL command DEBUG/KEEP, you
    can use the debugger RUN command at any time during a debugging
    session to start a program under debugger control. If you are in
    the midst of debugging a program when you issue the RUN command,
    that program will first be terminated unless you use the /NEW
    qualifier.

    To run the same program again (that is, the same version of the
    program that is currently under debugger control), use the RERUN
    command. RERUN enables you to save the current state (activated
    or deactivated) of any breakpoints, tracepoints, and static
    watchpoints.

    Note the following restrictions about the debugger RUN command:

    o  You can use the RUN command only if you started the debugger
       with the DCL command DEBUG/KEEP.

    o  You cannot use the RUN command to connect the debugger to a
       running program. See the description of Ctrl/Y.

    o  You cannot run a program under debugger control over a DECnet
       link. Both the image to be debugged and the debugger must
       reside on the same node.
