Thanks for the reply. The issue with the suggested code is that it
only considers a spell if harvest>0. I want the spell to include all
the non-harvest leading up to the harvest event.
And sorry for not mentioning the source: -tsspell- from SSC. It is a
great, and very useful, user written program.
Regards,
Steve
