Face-lifting HTML converters These allow you to enhance the HTML by extending it, or replacing it. Application Programming Interfaces These products make the existing screens ‘visible’ to a programming language, such that the programmer can use the host applications as background resources in new e-business applications written specifically for the browser users.

Three tier architectures Application Programming Interfaces e-business logic needs access to hosts The simplest Web API You remember GlAPI? and Perl? We married them and got… Cpic.pm Cpic7800.pm Cpic3270.pm Glapi.pm CpicDku.pm Any Web programmer knows Perl. It is free of charge, and supported on all platforms. It has an extensive library of free routines for almost all purposes, including HTML generation.
