[Genome] exon frame in genepred files

[Amit Indap]

Hi UCSC

I was looking at this message where Ann did a great
job explaining what exactly the exon frame fields mean
in genepred files.

http://www.soe.ucsc.edu/pipermail/genome/2006-November/012218.html

Pardon me if this is a silly question, but why
couldn't you just do (exonEnd-exonStart) % 3 to get
the frame?  

If the modulus result isn't 3, then does the exon pick
up the extra nucleotides  from the next exon in the
list or the exon before it? 

Thanks for the help!
