This function is the beginning marker for a "Loop" grouping level. During execution, each of the following Script Steps will be executed until reaching an "End Loop" statement. The Scrip will then branch back up to this marker and continue executing until an "Exit Loop IF" expression evaluates to TRUE, or the "Loop Repetition" number has been exceeded. A "Loop" statement can also be inserted into an existing "Loop" grouping level to create a sublevel. Note, all "Loop" grouping levels must be terminated with an "End Loop" statement.
