Questions tagged [qbasic]

QBasic is a general-purpose interpreted programming language derived from QuickBasic 4.5. QBasic replaced GWBasic starting from MSDOS 5. It became popular, because it had a quite advanced IDE with a debugger and was delivered free with MSDOS, Windows 95 and 98. The well-known game 'Nibbles' was written in QBasic. QBasic was written by Paul Allen (Microsoft) in 1991. Also see [tag:quickbasic]
