Works well. I appreciate the outdescrip and timedata, neither of which are provided by Tek's batch converter. Y-data agrees with Teks's batch converter out to 7 decimal place. The difference, like wfm2read.m, appears to be due to casting of DimScale and DimOffset when read from the file, but I couldn't fix this nusance without a floor(1e10*y)/1e10, so I'm not sure what the problem is.
