mm_vms.pm question.
In MM_VMS.PM, there is a comment that unixify will sometimes return a string with an off-by-one trailing null. And what does that mean? More than one null terminator? Do you have a reproducer for that problem? Thanks, -John [EMAIL PROTECTED] Personal Opinion Only

And what does that mean? More than one null terminator? Looks like it. I guess the length of the string reported in the SV was off-by-one possibly as a result of a regex bug or some XS code... though I don't see any obious XS code in VMS::Filespec. Do you have a reproducer for that problem? Hmm, that comment is fairly recent... r1245. 3.27.2003 unixify() has an intermittant off-by-one terminating null bug in 5.8.0. Working around. I don't see any mention of what the problem was on vmsperl and I don't remember what the problem was. If you're feeling daring you can cut that line out of your copy of MM_VMS and wait for the explosion. :)

More than one null terminator? Perl strings are roughly equivalent to dynamic string descriptors on VMS. The length is stored internally so you shouldn't see the null byte from Perl. It looks like there was a bad length calculation at some point or other problem that caused the length to include the null. This workaround apparently came into the core with the following patch, though may have been in an independent release of MM before that: http://public.activestate.com/cgi-bin/perlbrowse?patch=19099 Do you have a reproducer for that problem? No, but the following bug fix from just about a year ago may be related: http://public.activestate.com/cgi-bin/perlbrowse?patch=22544 http://www.nntp.perl.org/group/perl.vmsperl/12349 -- Craig A.
