I'm sorry but I do not know what to do here.  INDXR seems fine - I was 
confused.  When I try BLAPP in my debugger it gets into an infinite loop 
almost immediately.  The problem is that the task assumes that the BS 
table has been filled in properly.  Instead, many of the error columns 
are pure zero.  The weights are then infinite which causes no end of 
trouble.

Perhaps you should ask Walter Alef about this - he has much to do with 
MK4IN and may know about the BS table.  People around here have used it 
following BLING but were unaware of this mode.

I am curious about your data in other ways.  Many of the data samples 
have u = v = w = 3140.8928 which reminds me of magic blanks (although I 
am not exactly sure if the value).
