Could you please elaborate your requirement? Why you are looking for while and do while logics?

Consider I have an integer as a input and I apply condition on that integer. If condition returns true then end of the loop, else again check the condition with decremented value of integer.

As others have said you cannot break out of a loop in Appian, you have to let it run to the end of the provided list. Typically what I do is output 'null' when my condition is not met, and the value I do want when the condition is met, and then remove the nulls from the generated list.

Thank you, I will look into that.

Here's trivial example to illustrate the idea:

fn!reject(
  a!isNullOrEmpty,
  a!localVariables(
    local!myList: fn!enumerate(10) + 1,
    a!forEach(
      items: local!myList,
      expression: if(fv!item = 5, fv!item, null)
    )
  )
)
