There was an option "Var assigned but never used", which underlined me
litter from old days in red. Unfortunately I cannot find the option
any more. All hints are "checked" already.

Has anybody a hint for me?
Thanks.

It's a note, not a hint (see attached screenshot).

Other things that can hide this hint:
- if you put '{%H-}' in front of variable declaration
- if you put '{$WARN 5027 off : Local variable "$1" is assigned but
never used}' in your source file
- check if you filtered this type of messages in Message window: right
click in Message window and then Remove Message Type Filter
- check if you haven't filtered notes: right click Message window,
then 'Filter non urgent messages' and check if dot is below 'Filter
notes and below'

thank you!
It was unchecked, no idea why.

And I will keep your other hints, they are really useful.
