GUIEnvironment is a package which simplifies the creating and interacting with GUIs (Graphical User Interfaces). Using GUIEnvironment will save you a lot of time when writing applications which take use of the Amiga GUI, although the guienv.library is very small. Your ready to run application will of course later only need the library! ZedREXX provides users with the ability to quickly and easily build a graphical user-interface into any of their REXX scripts.
