ZBASIC is a BASIC compiler for 8-bit Apple II computers. These are the ProDOS versions, of which there are two. One is for 64K models, and one is for 128K models. Programs build using the 64K version run on any ProDOS-compatible Apple II; programs build using the 128K version require a 128K system. The language has a number of extensions for graphics and structured programming, a full-screen editor, a command-line interface, and the compiler itself. You can run programs directly in the ZBASIC environment or as standalone ProDOS applications. ZBASIC supports regular or Double Hi-Res graphics, allows you to integrate text and graphics, and to customize your graphics sets. It also suppors DO/UNTIL and WHILE/WEND commands, RAM disks up to 8 megabytes, and has full mouse support.
