Re: Anybody know what this USMARC.pm error is?

I think I figured out what was causing this.
(I still don't understand what is actually happening, but this made it work
like I expected.)

The copy of the bib records that I have are in a text file.  At some point,
some MARC-8 or UTF-8 characters got transcribed to multiple ASCII
characters.  Some of them are in the Leader bits 20-23.  That causes the
leader to expand one or two characters, throwing everything from there off.
I thought that the directory would correct that (unless the directory is
corrupted), but I guess only if it starts at bit 24 like it's supposed to.

Here's a sample from a problem record:
01545cam a2200433 a
45’000100060000000500170000600800410002301000170006401500150008101900230009602000290011902000320014802000230018002000250020302900180022803500230024604000

The accent (grave?) character in the line is the problem.
The attached file has three records.  I hope it keeps the damaged record if
you want to look at it.  It's the middle record, 001: 30778.

Ultimately, the problem was in my RegEx that I wrote to convert those
characters to the correct number of bits.  My substitution did not work the
way I expected it to.

substr($line,20,4)=~s/45(?:[0\D\s]){1,3}/4500/;

($line is a line from the text file holding a complete bib record.)

I failed to consider the case where this would end up inserting an extra 0.
("45A00"  The A should be removed not replaced.)

Suggestions?

Thanks to all who have tried to help.
Mike
