The WHILE...WEND statement is used to repeat a block of statements while the condition is met.
- condition is a numeric expression used to determine if the loop will execute.
- statements will execute repeatedly while condition is a non-zero value.
- EXIT WHILE can be used for emergency exits from the loop in QB64 only.
- A DO...LOOP can use the same DO WHILE condition to get the same results.
- WHILE loops only run if the WHILE condition is True.
