NOTE

       This qualifier is not available in the VSI DECwindows Motif
       for OpenVMS user interface to the debugger.

    Displays the source line corresponding to the location of each
    examined entity. The examined entity must be associated with a
    machine code instruction and, therefore, must be a line number, a
    label, a routine name, or the memory address of an instruction.
    The examined entity cannot be a variable name or any other
    address expression that is associated with data.

    In screen mode, the output of an EXAMINE/SOURCE command is
    directed at the current source display, if any, not at an output
    or DO display. The arrow in the source display points to the
    source line associated with the last entity specified (or the
    last one specified in a list of entities).

    On Alpha processors, the command EXAMINE/SOURCE procedure-name
    displays the source code at the code address of a specified
    routine, entry point, or Ada package.
