Hi @siowyisheng I traced through the code. The solution is a simple fix to simply remove pre v6 functionality of auto-appending brackets for code such as below. Since the assumption is not to have backward compatibility, then the following block of code should have indentation given by user already instead of assuming indenting once on user's behalf.

for n from 1 to 10
echo `n`

This fix is tested to be working for -

for m from 1 to 3
    for n from 1 to 3
        echo `m`,`n`

and

for n from 1 to 20
    if (a==1)
        for p from 21 to 40
            echo `n` - `p`

For your review if this change works for the earlier test cases you used for this feature.
