OTL Syntax

// While (do)
while (BooleanTerm) : WhileLoopName

//Do while
} while (BooleanTerm) : WhileLoopName


The OTX (do) WhileLoop activity contains a sequence of activities that are executed repeatedly until the condition evaluates to false. The expression for the condition is either before (while) or calculated according to (do while) the loop and tested.

Icons Note.png Please keep in mind that Do While at least once iterate loop!

The loop can be exited about the activities of break, return, or throw. The continue activity stops the current iteration and continues with the next iteration, without having to leave the loop.

Test Boolean Term - [1] Continue the loop condition expression

OTL Examples

Integer Integer1;

while (Integer1 < 10) : WhileLoop1
   Integer1 = (Integer1 + 1);

   Integer1 = (Integer1 + 1);
} while (Integer1 < 10) : WhileLoop2
