Loop Action - Nested Loops

[joe12]

It says in the Help: A Loop action cannot be nested within another Loop action.

I have a Loop Action that iterates over an ADO record set and calls a subroutine within the loop block. In that subroutine I have another Loop Action which also loops over another ADO record set.
Nesting seems to work ok using the subroutine mechanism of nested loops.


Why does it work using the subroutine but the help says nesting is not allowed?

What is the best way to handle nesting of loop actions and why are there restrictions on nesting of loops?
