[Orca-users] Re: number of columns does not match column descri ption (NOT)

[Blair Zajac]

Hi Mark,

I'd like to apply your patch to the latest orcallator.se.  Can you either
email me a diff -u patch against the version of orcallator.se you used or
email me the whole file so I can do the diff myself?

Best,
Blair
