The local news machine has been flaky, and I tried to send from another host, but I don't think it worked. In article <1991Jun14.140857.25984@mintaka.lcs.mit.edu> I wrote: >I'm not sure what the correct solution is [...] (Perhaps we should >just redefine \@mkpream to count the columns while it is constructing >the preamble?) After a little thought, I decided that this was relatively painless, since it involves modifying only the very macro which has been causing us troubles, namely \@tablcassz. At least, I think this is true. Can someone with a better understanding of the array code confirm (or deny) that my solution is robust? Diffs are included below. I can also send the entire new file to anyone who would prefer it that way. ------------------------------------------------------------------------------ David M.
