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...???

Answer 2

To open up an already saved QBASIC program file...so that you can either get to see it's contents/or else, RUN the program using function key [F5]...

Within the QBASIC IDE/Integrated Development Environment itself; try clicking the menu options above which say...

File > Open

...or, if you prefer using keyboard shortcuts...

[Alt] + [F], then, [O]

...this should open up a File dialog box...which allows you to see the both the current folder you are in/together with the files being listed inside of the File List box.

If you wish to change to a different folder; then, you need to use your mouse to select which particular drive/folder you would prefer to load QBASIC files from, instead.

USING FILENAME/OR ELSE, WILDCARD SYMBOLS TO SEARCH WITH

You can also search for particular files by typing the file name into the Filename box...

program1.bas

Or, if you're not sure exactly what the program name was that you saved/or else, you forgot...; you could try searching for program filename extension type, instead...

*.bas

...the asterix is a wildcard symbol which means show 'any'. In this case, the command is saying...show ALL files, in the current folder directory, containing 'any' file name; and, also, has 3 letter filename extension ending in: (.bas).

*NOTE* :QBASIC files are, normally, saved using:

[filename] + dot: [.] + [3 letter filename extension]

...the (.bas) filename extension indicates this is a QBASIC program type of file.

But, you can also search for files with different extension meanings, as well...

*.txt

...Text extension files

*.csv

...Comma Seperated Value files

*.dat

...DATA files

/-etc.

Another thing you can try is...

*.*

...which just means: show (ANY filename.ANY filename extension); or, in other words, show ALL files.

LAUNCHING QBASIC FROM INSIDE OF WINDOWS

Left double click on the program icon called:

qbasic.exe

...then, the QBASIC IDE/Integrated Development Environment will load.

The QBASIC IDE includes...

-> QBASIC Editor Screen (where you type in your programs)

-> QBASIC Output Screen (where you view your program output)

-> An Immediate Window(where you can evaluate a single line of QBASIC code)

-> QBASIC Help file(which can be launched by pressing function key: [F1]; the Help file includes a list of all QBASIC keywords; together with explanations, and, example QBASIC program codes that you can choose to 'copy & paste'; then, RUN)

Usually, the first screen that appears will ask you if you wish to see Help, first; to say, no; then, simply, press [ESC] key to continue...; this takes you straight into QBASIC 'blue' Editor Screen where you can type in your program. Type into QBASIC editor the following line of code.

PRINT "Hello, world! From QBASIC"

...in order to RUN/execute the program you just wrote; press function key [F5]...

...the 'black' Output Screen should suddenly appear; and, display the following text...

Hello, world! From QBASIC

Press any key to continue...

(Pressing any key...will return you straight back to QBASIC Editor screen; where you can further choose to either keep on Editing/changing your program...then, Re-RUN it/or else, you can chose to Save the program, instead...by using menu options: File > Save. Give the file a name...no more than 8 letters long...; then, click [OK] to save. A 3 letter filename extension will be automatically added on to each new QBASIC file you save: (filename.bas)

To reload a program that you've already saved...use menu options: File > Open...then, search to find the file you wish to load...find it inside of the File list box by clicking on it's name...then, press [OK] to load. Once the file is already loaded into QBASIC Editor screen; again, press function key [F5] to RUN.

USING MS DOS TO LAUNCH QBASIC PROGRAMS

It's also possible to launch QBASIC programs from the MS DOS command line by typing...

C:\>QBASIC.exe filename.bas

...where [filename.bas] is the name of any QBASIC program file which you care to load into the Editor Screen as soon as the QBASIC program starts.

Answer 4

With your mouse if you double-click on it from outside Qbasic. Otherwise, inside, you'd go to the File menu, select Open, and then open it. Then you can hit F5 to run it.
