Hi Alan, the problem was almost literally blindingly obvious, but I had to print out just about everything I could think of and then some. The mistake was that I called plscmap1n in gray_cmap with the argument num_col, instead of $num_col - so the name of the variable, instead of its value. With that corrected, I get a perfect match for example 20! Now, there are still the strange deviations in example 11. I am not sure how to proceed here - probably the same stubbornness as for example 20 is required :). But I am also thinking of how to implement example 19 - it should not be that difficult.
