QBasic — Windows 98 Simulator

Immersive experience (full screen)

Back in 1998

QBasic 1.1 came with MS-DOS 5 and later with Windows 95 and 98 (in \TOOLS\OLDMSDOS on the CD). For a generation it was the first programming language: the blue editor, the Gorillas and Nibbles demo games, and PRINT "HELLO" as a first program.

What you can do here

QBasic 1.1, the BASIC that came on the Windows 98 CD, in its blue full-screen IDE: type a program, press Shift+F5 to run it, F6 jumps to the Immediate window and F1 explains a keyword.

PRINT, INPUT, IF, FOR, DO, SUB and FUNCTION, arrays and strings, SCREEN graphics modes with LINE, CIRCLE, PAINT and DRAW, PLAY and SOUND music, and step-by-step debugging with F8, F10 and F9 breakpoints. Programs are saved as .BAS files on the simulated C: drive; type qbasic at the MS-DOS Prompt to start it there.
