Dear Koha Developers, I have noticed that Koha (probably) never displays "0" subfields in librarian MARC view (of course the subfield is not empty nor hidden and it is active). It is probably because of the line: $subf[$i][0] = "@" unless $subf[$i][0]; (line 165 of MARCdetail.pl). (A similar situation in case of line 134 of opac-MARCdetail.pl.) Isn't it a bug? Shouldn't the line be like: $subf[$i][0] = "@" unless $subf[$i][0] ne ""; ? But even if, what is the line for? If the subfield code is changed then probably the subsequent line will cause a 'next'...
