Code Folding - how to show vertical line?

Ninon_1977

Hi there :-)
My code folding works - from MSTART to MEND.
Anyhow, I am wondering how I can display the vertical line - see picture below.
Thank you for any help!

@Ninon_1977

is the first picture from a user-defined-language(UDL) or some builtin lexer?
If this is an UDL, how did you set the folding options?

Hi :-)

Thank you for your response!
I use UDL - and after some trouble shooting I found the solution/reason for this behaviour.
Above the text of my screenshot I had a comment called:

"MSTART
.
.
.
MEND

So the folding was closed but never opened.
After I deleted the quotes before MSTART it worked.
