process-name

    The process-name specifies the name of a process to which control
    transfers. The process must already exist, be part of your
    current job, and share the same input stream as your current
    process. However, the process cannot be your current process or a
    subprocess created with the /NOWAIT qualifier.

    Process names can contain from 1 to 15 alphanumeric characters.
    If a connection to the specified process cannot be made, an error
    message is displayed.
