Alan's changes also don't work. The len instrinsic returns the length of the fortran character array, not the actual length of the string. This means that, for example, passing a character array of len 8 which you have set to 'test ' will actually pass 'test ' to the C interface. This causes example 14 to fail when setting the driver since the padding spaces makes the name invalid. It also causes postscript regression on a large number of other examples.
