How To Write Program In Gw Basic 10 Class Computer Gw. Click Images to Large View 10th Class Unit 2 Gw Basic Commands Practical.It is a fundamental Computer programming language for beginners who want to become an expert computer programmer.Click on the Start, type basic, if GW-Basic will already be installed then click on it otherwise install it.Remember for different windows, gw-basic language installs with a different name.As for windows 7 or higher, it is PC-BASIC.There are two methods to type the programme in GW-Basic.In the direct method, we type the programme without line numbers and get the result just after pressing the enter key.In the indirect method, we type the programme with line numbers and get the result after executing the programme by using the RUN command or pressing the F2 keyWhile string value is anything which you type in “quotation marks”.Another example to learn about numeric and string valuesIn the above example, you will notice that the values under the quotation marks are displayed as it is , while you get the result of the values that are without quotation marks.There are two types of constants in GW-BASICNumeric constants are numbers that can be either positive, negative or zero and can also be fractional numbers expressed with decimal point. Those building blocks are –Constants – A constant is a term or value that does not change during program execution. BASIC stand for Beginners All-purpose Symbolic Instruction Code, the GW in GW-BASIC stands for Gee Whiz (which means Surprised) sometimes it is also said that GW is named after Greg Whitten (former Microsoft Chief Software Architect) who developed the translator for BASIC.Just like any other programming language BASIC has certain building blocks which are used to develop programs. GW-Basic stands for Gee-Whiz Beginners’ All-Purpose Symbolic Instruction Code and Graphics and Windows Beginner’s All-Purpose Symbolic Instruction Code.GW-BASIC Computer Science 10th V 2.1 Exercise Programming Problems Plus commands & functions Complied By.The value of a variable can change during the execution of a program. “Linkin Park”, “*123#”, “A”, “65536” etc…Variables – A variable is a memory location to store a constant. They may include alphabets, special characters, numbers or sentences. They can have a maximum length of 8 characters which can be both alphabets and numbers but they must begin with an alphabet and not a number. There are two types of variables in BASIC –Numeric Variables can store only numeric constants. A variable must start with an alphabet and can be maximum 8 characters long. The program line ends when you press the ENTER key.Depending on the logic of your program, there may be more than one statement on a line. Line numbers indicate the order in which the program lines are stored in memory, and are also used as references when branching and editing. After execution the command line is not stored anywhere and hence we say is lost but the values if assigned to any variable will still be resident in the memory and will be affecting the next command.Then the output will be 1000, this indicates that the value of A=10 has become memory resident and will be used as many times the command is issued in the prompt.In-direct Mode (Program Mode) – In this mode the GW-BASIC system will accept program statements one after another without actually executing them and will be executed all at once with a RUN command.GW-BASIC program line always begins with a line number and must contain at least one character, but no more than 255 characters. = Greater than or equal to, => can also be used for the same purposeLogical Operators are used to join two or more relational operators in BASIC, There are 3 different types of Logical operators AND, OR, NOT (more of this will be discussed in Chapters ahead)Modes of Operation – BASIC can operate in 2 different modes,Direct Mode (Command Execution Mode) – In this mode BASIC will accept one command at a time and immediately executes the typed command. Operators are of 3 different types in BASICArithmetic Operators are used to perform mathematical calculations on numeric quantities.Priority of Operators in GW-BASIC (High to Low)Relational Operators are used to perform decision making based on comparison between two or more quantities. A$, ABC$ N1$ etc…Operators – These are special symbols that are used for specific purpose. ![]() Commands in GW-BASICCommands in GW-BASIC can be broadly classified into two –System Commands are used to control and work in the direct mode, they are executed without any line numbers and are specifically to manage the working environment in BASIC, and on the other hand the Programming commands are implemented inside a program.NEW – This command is used to start a new program after removing previous ones (if any) from the primary memory of the computer (RAM)CLS – This command is used to clear the screen.AUTO – This command is used to generate automatic line numbers, by default the gap is 10. This process is called editing. The existing line is replaced with the text of the newly entered line. BAS at the end of the filename.LOAD – This command is used to load (copy) the program from Hard Disk to primary memory (RAM)RENUM – This command is used to re-number the line numbers if they are not in equal intervalsDELETE – This command is used to delete a line of code from the current program residing in (RAM)The above command will delete line number 30 from the current program.KILL – To delete a program file permanently from Hard DiskFILES – To display the list of BASIC files stored in Hard Disk LET & PRINT statements in GW-BASICIn GW-BASIC assignment can be done using LET command as well as direct assignment of variables without using the LET command. BAS in case the programmer does not provide the extension name the BASIC will automatically assign. Hard Disk.The extension name for a BASIC file is. RAM)SAVE – This command is used to save the current program from primary memory (RAM) to the secondary storage device (Hard Disk)Syntax: SAVE (The filename is to be provided within double quotes)The above command will save the current program from the primary memory to the secondary memory, i.e. RAM)RUN – This command is used to execute the program which is currently residing in the primary memory (i.e. Both the examples are shown below.
