In a While..Wend loop, if the condition is True, all statements are executed until Wend keyword is encountered. GW-BASIC is a dialect of the BASICprogramming language developed by Microsoft from BASICA, originally for Compaq. Each WEND matches the most recent WHILE. The language is suitable for simple games, … Control then returns to the While statement and condition is again checked. If it is not true, execution resumes with the statement following the WEND statement. The source code is also included with each tutorial, so you can run it, modify it and experiment with it. FoxPro just has the loop with While at the beginning so it is not possible to initialise the test condition inside the body of the loop. The loops are the While, Do Loop, and For loop.

For example, i = 0. 0 1 2. The process of displaying and … GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA.Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original IBM PC.It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft.. Example. The following Do Loop counts from 1 to 100. With the Break command it is possible to exit the While: Wend loop during any iteration, with the Continue command the end of the current iteration may be skipped. The structure of a While...Wend Loop is very similar to the Do Loop. In While-Wend loop the minimum number of iteration is ______. It is otherwise identical to Microsoft/IBM BASICA, but is a fully self-contained executable and does not need the ROM BASIC. WHILE and WEND loops may be nested to any level. . In this example, we add a list box to display a series of numbers and the sum of those numbers. WARNING Make sure that the loop has a condition that will end the loop. Microsoft also sold a BASIC compiler, BASCOM, compatible with GW-BASIC, for programs needing … Step 2 INPUT N1, N2, N3. GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA.It is functionally identical to BASICA, but is a fully self-contained executable and does not need the Cassette BASIC ROM. GW-BASIC then returns to the WHILE statement and checks expression. If the condition is false, the loop is exited and the control jumps to the very next statement after the Wend keyword. ; WHILE loops only run if the WHILE condition is True. A DO...LOOP can use the same DO WHILE condition to get the same results. Dim number As Integernumber = 1Do While number <= 100number = number + 1LoopA variable number is initialized to 1 and then the Do While Loop starts. GW-BASIC then returns to the WHILE statement and checks expression. Early BASICs (such as GW-BASIC) used the syntax WHILE/WEND.Modern BASICs such as PowerBASIC provide both WHILE/WEND and DO/LOOP structures, with syntax such as DO WHILE/LOOP, DO UNTIL/LOOP, DO/LOOP WHILE, DO/LOOP UNTIL, and DO/LOOP (without outer testing, but with a conditional EXIT LOOP somewhere inside the loop). ; statements will execute repeatedly while condition is a non-zero value. Be the first to answer! Sometimes, using CTRL BREAK (QBasic 1.1) can end the infinite loop. Example 15.4. WHILE and WEND loops may be nested to any level. Lets learn Using FOR … While--wend statement is used to execute a loop until a given condition is true.if the condition is false the loop ends and the program continous to the line following eend. EXIT WHILE can be used for emergency exits from the loop in QB64 only. If it is still true, the process is repeated. Visustin supports GW-BASIC in QuickBASIC mode. This tutorial will show the While loop. This flexibilty doesn't exist with While-Wend. This structure has the test at the start of the loop. These two statements comprise the start and end of a control loop. To execute a series of statements in a loop as long as a given condition is true. ; EXIT WHILE can be used for emergency exits from the loop in QB64 only. Using Do-Loop, you can put your test condition on the Do or on the Loop. The test variable must exist and have a value before the loop is … it takes the following form: While condition Statements Wend. Description. To execute a series of statements in a loop as long as a given condition is true. An unmatched WEND statement causes a "WEND without WHILE" error.

Visual Basic also has the separate While...Wend structure which has been retained for backwards compatibility with GW-BASIC. If it is still true, the process is repeated. Description. Step 3 DECISION IS N1> N2 AND N1 > N3 IF YES THEN PRINT N1. GW-BASIC 3.20 (1986) added EGA graphics support (no version of BASICA or GW-BASIC had VGA support) and was, in effect, the last new version released before it was superseded by QBasic. It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft. If it is still true, the process is repeated. If it is not true, execution resumes with the statement following the WEND statement. ; A DO...LOOP can use the same DO WHILE condition to get the same results. The tutorial includes many examples. When it gets to the Loop it goes back to the Do and tests condition again. Each Wend matches the most recent While. An unmatched WEND statement causes a "WEND without WHILE" error. If it is not True, execution resumes with the statement following the Wendstatement. If expression is nonzero (true), loop statements are executed until the WEND statement is encountered. WHILE and WEND loops may be nested to any level. If the condition is false, the loop is exited and the control jumps to very next statement after Wend keyword. If condition is still True, the process is repeated. Typical BASIC source code: These are the FOR-NEXT and the WHILE-WEND loops.
