    --|  NAME:  AC_SET_UP
    --|
    --|  OVERVIEW:
    --|    This procedure is only called if there is an existing input file.
    --|    The activity record is read from the input file by calling AC_READ.
    --|    Each record is added to the linked list by calling the generic List_Pkg
    --|    procedure ADD until there are no more activity records.
    --|
    --|  EXCEPTIONS HANDLED:
    --|    others  Error reading the record from the file.
    --|    .  This exception raises ERROR_IN_INPUT_FILE.
    --|
    --|  HISTORY:
    --|    written by   May Lee   March 1985
    --|
    --|  NOTES:
    --|    The number of activities records read in is determined by the
    --|    global variable num_of_activities.
    --|
    --|    If an error is detected reading the data, the rest of the input line
    --|    is skipped and reading the rest of the data continues.  All errors
    --|    found are reported.  Execution is not terminated until the entire
    --|    input file has been read.
