Microsoft QuickBASIC (also QB) is an Integrated Development Environment (or IDE) and compiler for the BASIC programming language that was developed by Microsoft. QuickBASIC runs mainly on DOS, though there was a short-lived version for the classic Mac OS. It is loosely based on GW-BASIC but adds user-defined types, improved programming structures, better graphics and disk support and a compiler in addition to the interpreter.

REM sample of bubble sort
N = 10
DIM A(N) AS INTEGER
FOR L = 1 TO N
    A(L) = INT(RND * 10 + 1)
NEXT
FOR X = 1 TO N
    FOR Y = 1 TO N - 1
        IF A(X) < A(Y) THEN SWAP A(X), A(Y)
    NEXT
NEXT
FOR L = 1 TO N
    PRINT A(L)
NEXT
