RJ edit

[gliderman.one at verizon.net]

I have two, two character fields.
One is  #  edit and one is  RJ edit.
Data entry is into the  #  field where (1)  is   1_. 
RJ  is filled  =  to the  #  field where (1) is   _1.
With  -v processing, I select a beginning and ending range of  RJ  and 
subtotal using the RJ field.

My processing using about 85 dummy data records works fine using the RJ 
edit.
Customer's processing containing about 4,000 records does not.  
Customer's  data  says it begins selecting records, but freezes without 
doing so.
Rebuilding the RJ index, deleting the RJ index and rebuilding it did not 
change the selection freeze. I looked for higher and lower ascii 
characters in a record but found none.
I changed the RJ field edit to .0 in the customer's file and  rebuilt 
the index.  It then worked fine.

Is there a rule that the RJ edited data will not sort properly; similar 
to the rule that the $ edit field  data should not be used to do math?
