I've written a program that performs many calculations each time it is executed. This program uses several hundred variables (located in about 15 modules) each time the program is executed. I'm looking for a way to empty all the variables in each module each time the program is executed. This is necessary to ensure the modules are using current information provided by the user each time the program is executed. Currently, I am attempting this manually ( setting each value to zero or "") but I'm finding this too time consuming. Any help is appreciated. Thanks in advance.
