Hi, I've found a bug in Ferret. Here's the example: --- Contents of data.dat: 2000 0.0 2010 0.0 --- --- Example script: file/var="year,data" "test.dat" let var1 = data[d=1] let var2 = if data[d=1] eq -1 then data[d=1] plot var1 ! Works plot var2 ! Works list var1,var2 ! Works plot var1,var2 ! Doesn't work! --- Plotting both variables individually works but plotting them together does not work. Ferret simply doesn't produce any output. This error only occurs when one variable is constant and exactly zero and the other one is missing everywhere. I've tested it with Ferret v6.401 and v6.6. As this is a very special case it's not a big issue, but it can break batch processing when an output metafile is expected but not found.
