QBASIC code/Editor Screen
(Press key [F5] to make the program RUN/execute...)
====
(Pressing any key returns you straight back to the Editor screen; where you can either chose to further Edit/Re-Run/or else, Save your program.)
Here is another example.
CLS
COLOR 15, 4, 14
PRINT "Press any key to continue"
DO WHILE INKEY$ = ""
LOOP
FOR c = 1 TO 20
COLOR c, 0
PRINT "Replace this with the name you want to display"
NEXT c
COLOR 15, 0
END
In QBasic, you can display a new line using the PRINT statement. To create a new line, you can simply use an empty PRINT statement. Here’s a simple example: PRINT "This is the first line." PRINT ' This will create a new line. PRINT "This is the third line." This program will display the first line, then move to a new line, followed by the third line.
The PRINT command in QBasic is used to display text and numerical output on the screen. It allows programmers to show messages, results of calculations, or any other information to users. By using PRINT, developers can effectively communicate the program's status or results, making it an essential tool for debugging and user interaction in QBasic.
To write a program in QBASIC to find the area of a square, you first need to prompt the user to enter the length of one side of the square. You can then calculate the area by squaring the length (multiplying it by itself) and finally display the result. Here's a simple example: INPUT "Enter the length of the side of the square: ", side area = side * side PRINT "The area of the square is: "; area
In QBASIC, you can continue running a program using the shortcut key F5. This key starts the execution of the program from the beginning or resumes it if it was previously paused. If you need to run a specific line, you can use the F8 key to step through the program line by line.
QBASIC keywords are reserved words that have special meanings and functions within the QBASIC programming language. They include commands like PRINT, INPUT, IF, FOR, NEXT, and END, which control the flow of the program and perform specific actions. These keywords cannot be used as variable names, as they are integral to the syntax and operation of QBASIC. Understanding these keywords is essential for writing effective QBASIC programs.
you do this 10 print "0112358132134" use the whole of the thing
END '...END of program/halt program code execution. *NOTE*: There should be only 'one' END statement written inside of a QBASIC program. I have seen example code where they use multiple END statements; this is wrong!

To stop a program from running in QBASIC, you can press "Ctrl" + "Break" on your keyboard. This interrupts the program execution and returns you to the QBASIC command prompt. Alternatively, you can close the QBASIC window to terminate the program. If you want to exit gracefully, you can also use the END statement in your code to stop execution at a specific point.

(1) Immediate mode In this mode, QBASIC performs the command/instruction that we type in immediately after we press the enter key. (2) Program mode In this mode, the instructions/commands we type in are not performed as we type them in, but are first stored in the computer memory as a program. This program can be executed later, at a high speed.

If you are using windows, MSDOS shell is integrated by default..

a triangle then a square :)
