The TYPE command displays the lines of source code that
    correspond to the specified line numbers. The line numbers used
    by the debugger to identify lines of source code are generated by
    the compiler. They appear in a compiler-generated listing and in
    a screen-mode source display.

    If you specify a module name with the TYPE command, the module
    must be set. Use the SHOW MODULE command to determine whether
    a particular module is set. Then use the SET MODULE command, if
    necessary.

    In screen mode, the output of a TYPE command is directed at the
    current source display, not at an output or DO display. The
    source display shows the lines specified and any surrounding
    lines that fit in the display window.
