A method executed by a computer under the control of a program includes the step
of linking an application program module with a corresponding integrated documentation
module. A single window displays an application program module region and an integrated
documentation module region in such a manner that the application program module
region can be fully viewed. The application program module is compiled without
compiling the integrated documentation module. The integrated documentation module
region may be turned-off and the application program module region may be re-sized
to substantially fill the single window.
