Hi Alan: I did correct some perl roundoff errors as part of fixing up x02.pl, but I've checked these changes in.
Right now from my build of plplot, I don't see any difference in the postscript output: cd examples c/x02c -dev psc -o x02c.ps perl/x02.pl -dev psc -o x02perl.ps diff x02c.ps x02perl.ps 6c6 < %%CreationDate: Fri Dec 5 10:26:34 2008 --- > %%CreationDate: Fri Dec 5 10:26:50 2008 In particular, the line: 1.0000 0.0745 0.0745 C Z is present in both postscript files. I seem to have checked everything in to the plplot SVN, and I don't think there is any difference in our PDL-Graphics-PLplot-0.42 drivers. I don't know how you run your 'ctest' suite. Maybe there is some difference there? Is it possible you are running with an old x02.pl? Regards, Doug [EMAIL PROTECTED] Software Engineer III UCAR - COSMIC, Tel.
