Admin and Bruce,

thank you for your replies.

My question stems from this post on the Gambas One forum:
https://gambas.one/forum/index.php?page=topicview&type=findpost&id=13792
The question was about how to construct and read a jagged array, and the 
answer above favored For Each over a simple loop with a counter.
Since I know this is true for certain languages, I wanted to know if it 
was also true for Gambas.

If I understand Bruce's answer correctly, using counters is preferable 
with Gambas.
