-chewfile- would be one line for the user. I'll even write the help 
file and send it to Kit.
ICD-9 codes are triple digits plus at least two decimals, depending 
on the flavor. You need to put back one or two leading zeros, plus 
worry about the floating points, and still not get it right because 
the number of decimals could be moving up and down.
