DO...LOOP

The DO...LOOP command is used for repeatedly executing a block of statements. It creates a loop, which is a sequence of statements that is executed repeatedly, forever (unless exits using the EXIT keyword). You can nest DO LOOPs within other loops, creating more complex control structures.

If you want to repeat the statements a set number of times, the FOR...NEXT statement is usually a better choice, while if you want to repeat for specific conditions, you should use the WHILE...WEND and REPEAT...UNTIL statements.

If you want, you can use a variant of the DO...LOOP command by adding the keywords WHILE or UNTIL to the end of the LOOP statement. In this case, the loop will be repeated until the condition is true or false, respectively.
