The code in question was printf OUT "$in1$in2\n" I thought 'printf' was wrong because it wasn't using print formatting at all: the scalar variables would be interpolated into the (then constant) format string. It make sense to me to write either print OUT "$in1$in2\n" or printf OUT "%s%s\n", $in1, $in2 but not a combination of the two.
