PRINT SQR(9)
...output...
3
(Thus, giving you the square root of the number 9; I presume this what your question meant...?)

In QBASIC, the Sign function is used to determine the sign of a numeric expression. It returns -1 if the number is negative, 0 if the number is zero, and 1 if the number is positive. This function helps in making decisions based on the value's sign in conditional statements or calculations.
the extensions of qbasic are that, there are only 80 pixels to write in the qbasic
qbasic is important because its technology
It meant nothing. You have probably confused an inscription reading SPQR. See the related question for the meaning.
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...???
There is no shortcut key of input in qbasic
Difference between QBASIC and GWBASIC?
The different types of operators in QBASIC are:Arithmetic OperatorsRelational OperatorsLogical Operators
In QBasic, a count mismatch error occurs when the number of arguments provided to a subroutine or function does not match the number expected by that subroutine or function. This can happen if too few or too many arguments are supplied, or if the data types of the arguments do not align with what is required. To resolve the issue, ensure that the correct number and type of arguments are being passed when calling the subroutine or function. Debugging and checking the subroutine definition can help identify where the mismatch occurs.
Qbasic and Quickbasic are not the same! Qbasic was a free interpreter that Microsoft included with MS-DOS. Although Quickbasic uses similar syntax as quickbasic it allows programs to be compiled.
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.
