John Kemeny and Thomas Kurtz originally developed it at Dartmouth College around the mid -1960 s.It soon became very popular because of its simplicity .Later ,others followed it and developed MS-BASIC,GWBASIC, BASICA and QBASIC.Initally ,Micrisoft Corporation developed MS-BASIC. Writing programs and getting results was a slow process  and to overcome this limitation ,Microsoft developed its faster version QBASIC .Full form of QBASIC is Quick Beginners All Purpose Symbolic Instruction Code. It is simple and easily available. QBASIC has an inbuilt editor .Editor helps in creating ,editing and storing text program files.We can create ,execute and debug a program without leaving QBASIC which speeds up our work. How to start QBASIC : It can be started as stated below : 1.By double clicking QBASIC icon on the desktop ,if it exists on the desktop . 2....
