MESSAGES

Just prior to return to CTM, if a new master tape was created, a list of the files in order of appearance on the tape is printed on-line. If an error is detected, a message of the form:

(MESSAGE) LAST CHANGE AT Name Nnnn PRESS START TO CONTINUE

is printed, and a pause occurs to allow operator action. The messages which may print are:

  1. CANNOT FIND FILE 'name'

    Either 'name' is mis-spelled or the *FILE card is out of order. In either case, if the start button is depressed, the program continues as if an *END card had been encountered.

  2. CHANGE READ ERROR

    Permanent read redundancy on the input tape. The program will continue, accepting the input as it stands, if the start button is depressed.

  3. OLD MASTER READ ERROR

    Permanent read redundancy on the input tape. The program will continue, accepting the input as it stands, if the start button is depressed.

  4. *FILE CARD MISSING

    The first card of a file on the master tape is not a *FILE identifier or an *END card. The program will continue normal operation if the start button is depressed. The master tape should be replaced, however, since modifications to the file with the missing identifier are not possible.

  5. *ALTER OUT OF SEQUENCE

    If the start button is depressed, the out of sequence set is ignored and normal operation continues.

  6. MAJOR CONTROL MISSING

    The first card of the change sequence is not a major control card. If the start button is depressed, the program continues normally, ignoring all changes cards prior to the first major control card. This occurrence is normal if the input tape was prepared as the second output of a previous update for which the C option was not used, since some *FILE identifier card must alwyas be first on such a tape.
