in the first part of your program (after keying in the inputs, place some code to have it open a new drawing, then load the inputs. This all depends on the language in which the program was built upon, but generally speaking, Visual Basic, and even Lisp routines run on a sequential method (FIFO - First in first out). C++ and all variances thereof are more of a random method (more powerful, but a bit more complex in the design of the application).
Hope this helps
