I'm working on bug #35. I'd like to combine some of the different "styles" of boolean questions so that they are all "yes/no" type questions. Right now we have three different styles: yes/no 1/0 on/off I've done a search of all .pl and .pm files and found the following list of locations that use preferences. Some of these will have to be changed (notably, 'marc', 'autoMemberNum', and 'autoBarcode') to reflect the change to a "yes/no" value. If nobody objects to any of this, I'll carry on. You can take a look at the systempreferences page at: http://142.28.224.19/cgi-bin/koha/admin/systempreferences.pl ./cgi-bin/acqui/acquire.pl: autoBarcode ./cgi-bin/acqui/newbiblio.pl: autoBarcode ./cgi-bin/admin/thesaurus.pl: authoritysep ./cgi-bin/value_builder/unimarc_field_210c.pl: authoritysep ./cgi-bin/value_builder/unimarc_field_225a.pl: authoritysep ./cgi-bin/loadmodules.pl: acquisitions ./cgi-bin/loadmodules.pl: marc ./cgi-bin/mainpage.pl: marc ./cgi-bin/search.pl: marc ./cgi-bin/acqui.simple/addbooks.pl: marc ./cgi-bin/acqui.simple/isbnsearch.pl: marc ./modules/C4/Circulation/Circ2.pm: noissuescharge ./modules/C4/Auth.pm: timeout ./modules/C4/Auth.pm: insecure ./modules/C4/Authorities.pm: authoritysep ./modules/C4/Boolean.pm: insecure ./modules/C4/Breeding.pm: marcflavour ./modules/C4/Date.pm: dateformat ./modules/C4/Input.pm: checkdigit ./modules/C4/Members.pm: autoMemberNum ./modules/C4/Output.pm: opaclanguages ./modules/C4/Output.pm: opaclanguages ./modules/C4/Output.pm: template ./modules/C4/Output.pm: opacthemes ./modules/C4/Output.pm: theme ./modules/C4/Output.pm: allowthemeoverride ./modules/C4/Output.pm: languageorder ./modules/C4/Print.pm: printcirculationslips ./modules/C4/Print.pm: printreserveslips ./modules/C4/Print.pm: printcirculationslips
