     The first question is why are you running MX?  It is obsolete and
has had no attention paid to it in many years.

    In IMAGR, errors like this have been dealt with - they arise from
a failure in the histogram methods used to determine which pixels to
load to the "AP".  Usually they arise only when the beam itself has
problems such as high values in the corners.

     This says that the input data set (catalog number 35) does not
have a HIstory file.
