      [parameters]

    "title"     Title to display in window title bar.
    path        Starting directory.
    B           Start application without creating a new window. The
                application has ^C handling ignored. Unless the application
                enables ^C processing, ^Break is the only way to interrupt
                the application.
    I           The new environment will be the original environment passed
                to the cmd.exe and not the current environment.
    MIN         Start window minimized.
    MAX         Start window maximized.
    SEPARATE    Start 16-bit Windows program in separate memory space.
    SHARED      Start 16-bit Windows program in shared memory space.
    LOW         Start application in the IDLE priority class.
    NORMAL      Start application in the NORMAL priority class.
    HIGH        Start application in the HIGH priority class.
    REALTIME    Start application in the REALTIME priority class.
    ABOVENORMAL Start application in the ABOVENORMAL priority class.
    BELOWNORMAL Start application in the BELOWNORMAL priority class.
    AFFINITY    The new application will have the specified processor
                affinity mask, expressed as a hexadecimal number.
    WAIT        Start application and wait for it to terminate.
    command/program
                If it is an internal cmd command or a batch file then
                the command processor is run with the /K switch to cmd.exe.
                This means that the window will remain after the command
                has been run.

                If it is not an internal cmd command or batch file then
                it is a program and will run as either a windowed application
                or a console application.

    parameters  These are the parameters passed to the command/program.

NOTE: The SEPARATE and SHARED options are not supported on 64-bit platforms.
