Hi Juan
You can get barcode font code39 from www.abcfont.com
You have to put * sign before and after the numbers. The detail in available on WWW.ABCFONT.COM There is also a complete detail on "Barcode Made Easy in FoxPro" in FoxPro Advisor magazine (Oct 2000) you can get this old copy from WWW.ADVISOR.COM email order@advisor.com There was reference of code39 free download. The magazine is not with me now I can send you the links after two days after checking the magazine.
Thanks
