[V4MD 2] update only one field in a loop

[info at vallemediatime.com]

Hi Ruslan,
if I need to update only a field of DB for n records what is the better way?

e.g.
repeat with i = 1 to recCount
gCursor.field("F1").value = member("F1").text
gCursor.updateRecord() -- LOOK HERE
end repeat

In your docs I read the word nil
I know null but nil... what means?

Thanks
Paolo
