Embodiments of the present invention provide a method, system and computer program product for extensible definition of interactive system productivity facility (ISPF) panels. In an embodiment of the invention, a method for extensibly defining ISPF panels can include loading a panel defined by different panel definition statements recognizable by an ISPF facility, and identifying a panel input exit facility amongst the panel definition statements defining the panel. Of note, the panel input exit facility references an external exit module. The method also can include determining an external exit module referenced by the panel input exit facility. Finally, the method includes passing records of the panel to the external input exit facility for pre-processing of the panel outside of the ISPF facility.

A method, apparatus, and article for solving the year 2000 problem involves limited modifications in the data definition portions of the source code and compiler support for processing the modified source code. Fields in the source code that contain a year or date values are identified and, for each such field, the user selects an appropriate technique (for example, expansion, compression or windowing). The user modifies the data definition for each identified field, by adding new attributes to request the selected technique. The user then compiles the program and resolves any ambiguous references to the variables whose definitions were modified. This procedure is applied, module by module, and each processed module is merged into production, after testing, by using a compiler option to disable the use of the new attributes. A compiler option provides for the generation of debugger hooks for each statement that has been affected by modified declarations, which may be used with a suitably equipped debugger or other run-time analysis tool.
