IF THE QBASIC IDE/INTEGRATED DEVELOPEMENT ENVIRONMENT *IS* ALREADY OPEN Inside of QBASIC IDE/Integrated Development Environment...; you load in QBASIC programs as follows... 1. Use your mouse to click the QBASIC Menu option being seen top right... File > Open ...then, browse through the file list box to load your chosen program file. 2. Alternatively, you can also use keyboard short cut... [ALT]+[F], this opens up the file menu...then, press [O] ...does exactly the same as above IF THE QBASIC IDE/INTEGRATED DEVELOPMENT ENVIRONMENT IS *NOT* ALREADY OPEN 3. Another way is to open up a command line window prompt: (>)... Click [Start] button ...then, type: Command .../or, type: Cmd ...at least, one of the above should work... ...and, run the QBASIC program from there... by typing in after the command line prompt: (>)... c:\> cd, means, change directory folder... cd C:\pathToQbasic For example the file path name to where my version of QBASIC is stored here... c:\basic\qb64 So, I would first change to this folder directory by typing in after the prompt: (>)... c:\>cd c:\basic\qb64 ...this changes my command line prompt: (>) to say... c:\basic\qb64> Inside of the [qb64] folder directory, I wrote a very simple program called: hw.bas ...which contains the following single line of code... PRINT "Hello, world!" I can launch both the QBASIC program: [qb64.exe]/and, at the same time load in my chosen program file: [hw.bas], by typing after the command line prompt: (>)... C:\Basic\qb64>qb64 hw.bas ...the QBASIC program instantly loads: [qb64.exe]/with the program file [hw.bas] already being displayed inside of the Editor Screen. Next, I only need to press function key [F5] to RUN/make that program file execute... QBASIC Output Screen... Hello, world! Press any key to continue...
Statement numbers were a feature of BASIC, and while QBASIC supports them, they are by no means necessary.
The advantage of qbasic is that it is easy to learn, to start out,then one can move on to more complex, or advanced languages.
QBASIC GRAPHICS There any many different things you can draw in QBASIC; ranging from... -dots -lines -rectangles -circles -shapes empty/or, filled in(painted) -you can even do LOGO style programming to draw graphics with; by joining up connected lines -animations are possible, too ==== QBASIC BUILT-IN HELP FILE + CODE EXAMPLES In order to view the QBASIC built-in Help file...; first, load the QBASIC program itself...; and, then, do a combination key press of: [SHIFT] + [F1] Use the built-in QBASIC Help file to learn more about how to use these 'graphic related' commands, and, more...! The QBASIC Help file also contains plenty of 'example codes'; which you can just use 'copy & paste'; then, RUN...to see what the output effect will be...???
