You may know more about sprintf's formats than me, but adding an extra % , as you suggest, dosn't change the behavior at all. Can you explain why?

    If you use the warnings pragma you'll find that the original code produces the following error

    Invalid conversion in sprintf: "%)" at test.pl line 16.

    The sprintf function documentation specifies that a percent sign should be formatted '%%'. I'm not sure why excluding the extra '%' doesn't count as a syntax error.

    From what I can tell the warning has been emitted via warnings since around 5.8.0. FYI I'm using 5.8.7 from Ubuntu 6.06 with the patch "SPRINTF0 - fixes for sprintf formatting issues - CVE-2005-3962." This patch is applied by either the Debian team or Ubuntu team (not sure which one). I think the patch originated from http://www.cpan.org/modules/by-module/Compress/NWCLARK/sprintf-5.8.7.patch.

    So you might not be wrong per-se but sprintf in versions of Perl without this patch certainly don't do what the manual says it should.

    Cheers,

      Thanks, I should have been using strict and warnings.
