In QBasic, the GOTO
statement is used to transfer control to a specific line in a program, allowing for non-linear execution. It can direct the program flow to any labeled line, facilitating loops or conditional branching. However, excessive use of GOTO
can lead to "spaghetti code," making programs harder to read and maintain. Therefore, it's generally recommended to use structured programming constructs like loops and conditionals instead.
Difference between QBASIC and GWBASIC?
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.
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.
In order to Download Qbasic you may do one, both or none of these two things: 1.) Go to "http://www.softpedia.com/get/Programming/Coding-languages-Compilers/Qbasic.shtml" and click download or 2.) use "Google.com" with the keywords Qbasic free download to find another website with a free qbasic downlaod.
QBASIC free downlaods are from cnet.com or softepedia.com.Hope this is helpful to you..... if u want anything else just mail it to rockmayur@live.com..
In QBasic, a label is a named identifier that marks a specific line in the code, allowing for easy reference and control flow manipulation. Labels are defined by a name followed by a colon (e.g., LABEL_NAME:) and can be used in conjunction with statements like GOTO or GOSUB to direct the program's execution to that point. They help in organizing code and managing loops or functions. However, excessive use of GOTO with labels can lead to "spaghetti code," making programs harder to read and maintain.
the extensions of qbasic are that, there are only 80 pixels to write in the qbasic
"GOTO" . . . goes to the line number or label indicated, continues program execution from there,forgets where it came from and never looks back."GOSUB" . . . goes to the line number or label indicated and continues program execution from there,but remembers where it came from; as soon as it reaches a "RETURN" command, returns to the commandthat immediately follows "GOSUB".
qbasic is important because its technology
10. input number 20. let accumulator = 0 30. if number > 0 then goto 80 40. let digit = number % 10 50. let accumulator = accumulator * 10 + digit 60. let number = number / 10 70. goto 30 80. print accumulator
There is no shortcut key of input in qbasic

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.
