Do statement (LotusScript® Language)
Executes a block of statements repeatedly while a given condition is true, or until it becomes true.
Syntax 1
Do [ While | Until condition ]
[ statements ]
Loop
Syntax 2
Do
[ statements ]
Loop [ While | Until condition ]
Elements
condition
Any numeric expression. 0 is interpreted as FALSE, and any other value is interpreted as TRUE.
Usage
In Syntax 1, condition is tested before entry into the loop, and before each subsequent repetition. The loop repeats as long as condition evaluates to TRUE (if you specify While), or until condition evaluates to TRUE (if you specify Until).
In Syntax 2, condition is tested after the body of the loop executes once, and after each subsequent repetition. The loop repeats as long as condition evaluates to TRUE (if you specify While), or until condition evaluates to TRUE (if you specify Until).
Terminating the loop
You can exit the loop with an Exit Do statement or a GoTo statement. Exit Do transfers control to the statement that follows the Do...Loop block; GoTo transfers control to the statement at the specified label.
If you do not specify a While or Until condition, the loop will run forever or until an Exit??Do or a GoTo statement is executed within the loop. For example, this loop executes forever:
Do
' ...
Loop
