WEND ==== PURPOSE ==== This instruction define a conditional loop, or a list of statements that will be executed while an expression is true. ''WHILE'' acts as the starting position while ''WEND'' as the ending one. This command provides a convenient way of making the program repeat a group of instructions all the time a particular condition is true. The condition is checked again at every turn of the loop, until it is no longer true. ==== EXAMPLE ==== WHILE alive : score = score + 1 : WEND See also the following example files: * ''[[https://github.com/spotlessmind1975/ugbasic/tree/main/examples/control_loops_04.bas|control_loops_04.bas]]'' ==== ABBREVIATION ==== Wh...We ==== AVAILABLE ON ==== * Atari (400/800) * Atari XL/XE * Commodore 128 (MOS 8502) * Commodore 128 (Zilog Z80) * Commodore 64 * Commodore 64+REU * TRS-80 Color Computer * TRS-80 Color Computer 3 * ColecoVision * Amstrad CPC 664 * Dragon 32 * Dragon 64 * Thomson MO5 * Thomson MO5 * Olivetti Prodest PC128 * Commodore PLUS/4 * SEGA SC-3000 * SEGA SG-1000 * VG-5000 * Commodore VIC-20 * ZX Spectrum 48 ==== ANY PROBLEM? ==== If you have encountered a problem using this command, if you think there is a bug or the explanation is unclear, please [[https://github.com/spotlessmind1975/ugbasic/issues/new?title=ISSUE ON WHILE...WEND|open an issue]] for this keyword on GitHub.
