    --|  NAME:  EL_ADD
    --|
    --|  OVERVIEW:
    --|    This procedure sets up the record to be added to the list by
    --|    user prompt/response.  The function calls to Prompt_Pkg return
    --|    only valid existing data.  The complete record is
    --|    then added to the linked list by calling the procedure
    --|    ADD_RECORD_TO_LISTS.
    --|
    --|  EXCEPTIONS HANDLED:
    --|    none
    --|
    --|  HISTORY:
    --|    written by   May Lee   March 1985
    --|
    --|  NOTES:
    --|    The number of elements is incremented if the element has been
    --|    successfully added to all the necessary data lists.
