if you have 255 fields in one table, it's very likely that your table is not
normalized. most experienced developers I've seen address this issue say
that a reasonable upper limit for a properly normalized table is around
25-30 fields. i really recommend you read up on table normalization,
otherwise you're going to have a terrible time trying to manage that much
data, and a lot of difficulty trying to leverage the power of the Access
software.
