Powerbasic

PowerBASIC for Windows is a native code compiler for all versions of Windows, from Windows 95 to Windows 10. It creates standard Windows GUI (graphical user interface) applications. It creates highly efficient executables and industry-standard DLLs for optimum flexibility. The machine code generated by PowerBASIC is among the most efficient in the industry, both in size and speed. Create applications that run in the Console (the "DOS box") under Windows. It's as straightforward as programming for DOS, yet gets you beyond those DOS limitations.
