• The block statements If...Then...Else, If...Then...ElseIf, and Select Case

  These specify executing a group of subsidiary statements, depending on specified conditions.

• The branching statements GoTo, If...GoTo...Else, On...GoTo, GoSub, On...GoSub, and Return

  These specify continuing execution at some other point in the script, possibly depending on specified conditions.

• The iterative block statements Do, For, ForAll, and While

  These specify repeating a group of subsidiary statements some number of times, or while or until some specified condition is satisfied.

• The early termination statements End and Exit

  These specify returning from a procedure, or ending execution of a Do, For, or ForAll statement, before execution reaches the statement that ends the procedure or the statement.

There is no built-in limit on the level or type of nesting of these statements. For example, a Do statement may contain another Do statement that contains a third Do statement, or a Do statement may contain a For statement that contains another Do statement.
