in reply to Re^5: do until loop breaks before meeting the condition
in thread do until loop breaks before meeting the condition

To: choroba,

You are right, I did not pay attention to the detail that you where pointing out:

Based on this modification works just fine.

Thank you for your time and effort assisting with my problem.
