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. Movie, Film and celebrities related databases, Public and Bank Holidays in every country in the World in 2021. The dialect of Basic that I use in this first part is based on the extended Basic named GW-BASIC or BASICA that comes with the IBM PC and most compatibles. If condition is True, all statements are executed until the Wend statement is encountered.

WHILE condition. GW-BASIC is a dialect of the BASICprogramming language developed by Microsoft from BASICA, originally for Compaq. It is otherwise identical to Microsoft/IBM BASICA, but is a fully self-contained executable and does not need the ROM BASIC. statements will execute repeatedly while condition is a non-zero value. An unmatched WHILE statement causes a "WHILE without WEND" error The Do While...Loop is used to execute statements until a certain condition is met. Lets learn Using FOR … First, the condition is tested; if condition is True, then the statements are executed. It was bundled with MS-DOS operating systems on IBM PC compatibles by Microsoft. Using Do-Loop, you can put your test condition on the Do or on the Loop. To execute a series of statements in a loop as long as a given condition is true. If the condition is false, the loop is exited and the control jumps to the very next statement after the Wend keyword. These two statements comprise the start and end of a control loop. Step 1 START. GW-BASIC then returns to the WHILE statement and checks expression. If it is still true, the process is repeated. PRINT USING and LPRINT commands. Known limitations with GW-BASIC: The NEW, LOAD and MERGE commands have no … Be the first to answer! WHILE and WEND loops may be nested to any level. 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. A Repeat loop is executed at least once, (as the test is performed after each loop). For example, i = 0. When it gets to the Loop it goes back to the Do and tests condition again. Basic has a loop in exactly this style. Dim number As Integernumber = 1Do While number <= 100number = number + 1LoopA variable number is initialized to 1 and then the Do While Loop starts. An unmatched WEND statement causes a "WEND without WHILE" error. If it is still true, the process is repeated. In this example, we add a list box to display a series of numbers and the sum of those numbers. Each WEND matches the most recent WHILE. WHILE and WEND loops may be nested to any level. It's been about 20 years since I last did something in GW-BASIC, but: a while-wend loop is a construct that allows you to iterate (loop) until a condition is met. While Loop Syntax WHILE [condition] [Statement Block] WEND Code Download Step 5 ELSE PRINT N3. condition is a numeric expression used to determine if the loop will execute. If it is still true, the process is repeated. The tutorial includes many examples. Consider the following program (note that str_My_Number should be the name of a text box): My_Number = Val (str_My_Number) i = 0 While i <> My_Number i = i + 1 Wend Print "I think that your number is "; i. BASIC. Visual FoxPro Syntax Notes. Each WEND matches the most recent WHILE. ; A DO...LOOP can use the same DO WHILE condition to get the same results. Example 15.4. (gw-basic)? Each WEND matches the most recent WHILE. 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. ; statements will execute repeatedly while condition is a non-zero value. Description. Visustin supports GW-BASIC in QuickBASIC mode. Each WEND matches the most recent WHILE. An unmatched WHILE statement causes a "WHILE without WEND" error. Step 6 … GW-BASIC then returns to the WHILE statement and checks expression. Step 3 DECISION IS N1> N2 AND N1 > N3 IF YES THEN PRINT N1. GW-BASIC then returns to the WHILE statement and checks expression. Example. Buyers of Hercules Graphics Cards received a special version of GW-BASIC on the card's utility disk that was called HBASIC and which added support for its 720×348 monochrome graphics. Visual Basic also has the separate While...Wend structure which has been retained for backwards compatibility with GW-BASIC. WHILE-WEND loops. WHILE and WEND loops may be nested to any level. GW-BASIC was designed for the IBM PC and is similar to IBM BASICA language, but is a self-contained executable and unlike other BASIC derived languages; it doesn't need the ROM BASIC. IBM BASICA and GW-BASIC are largely ports of MBASIC version 5.x, but with added features specifically for the IBM PC hardware. If expression is nonzero (true), loop statements are executed until the WEND statement is encountered. If there is not a condition to end the loop, the computer will be sent through an infinite loop. What is the purpose of wend statement in while loop in gw-basic? Should your GW-BASIC code contain QB-specific keywords you may see limited side effects in the charts. The loops are the While, Do Loop, and For loop. Microsoft also sold a BASIC compiler, BASCOM, compatible with GW-BASIC, for programs needing … Each Wend matches the most recent While. This tutorial will show the While loop. WHILE and WEND loops may be nested to any level. . 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.
