High performance code optimization in the IBM C Set/2 C compiler provides the opportunity to produce some of the highest-performing OS/2 based applications possible. Extensive runtime library support, online hypertext reference information, conformance to ANSI and SAA standards, and a fully graphical full-function source-level PM debugger all make C Set/2 an excellent choice for developing 32-bit OS/2 2.0 applications. Organizing C Set/2 projects in WorkFrame/2 further enhances programmer productivity.
