IGNORE

        CLIC\IGNORE list_of_observations

    This command can be used to declare the specified list  of  Observations
    (from the input file) to be ignored in all FIND operations.  They effec-
    tively become invisible to CLIC (except in a LIST IN command),  until  a
    FILE  IN command is typed again.  The input file is not physically modi-
    fied however.  The list of observation can be given using the same  for-
    mat as with a FOR command (e.g. n1 n2 n3 TO n4 BY n5 n6 TO n7).
