    HyperCP is performing a sensitive search for direct CP violation by
    comparing the angular distribution of the proton in the lambda helicity
    frame from the sequential cascade-lambda decay to the anti-proton from
    the corresponding anti-process. A difference in these distributions would
    be a signal for direct CP violation. HyperCP took data in the Fermilab
    fixed target run that ended in September, 1997. Over one billion
    charged cascades and 0.3 billion charged anti-cascades were collected.
    Based on this event sample, HyperCP expects to measure the hyperon CP
    violation asymmetry with an uncertainty of about 2 X 10**-4. Results from
    a preliminary analysis of approximately 10% of our data will be presented.
