Hi, I read these words in the PLT DrScheme: Programming Environment Manual: "choose the Create Executable... menu item from the Scheme menu. You will be asked to choose an executable file name or an archive file name." and "The result of Create Executable... is either a launcher executable, a stand-alone executable, or a distribution archive, and it uses either a MzScheme (textual) or MrEd (graphical) engine. For programs implemented with certain languages, Create Executable... will prompt you to choose the executable type and engine, while other languages support only one type or engine." However, when i clicked the "Create Executable" button, there's no other prompts such as "choose an archive file name" except the only choice to create an .exe file. I mean I can not create a distribution archive, no choice to do so. Why? Are there some tools missing? Or some tricks to do so? Please help. Thanks! Day
