Thanks to the group for the info on my ACCUM block reset question. Adding the CP_STA:STATION.MINUTE.~X0000 to the CLEAR param was a simple solution for us, plus I actually learned a few things yesterday. I didn't know that there were extension "logic" options. (Francisco was kind enough to forward me a few pages from chapter 6 in B0193AW describing the available extension options.) I had also made that bad assumption that as long as the CLEAR was TRUE the block didn't accumulate.
