Is it possible to display vertical lines according to settings requested e.g. at columns 8, 12, 16, ... 72. This would help greatly in formatting COBOL code.

I'm not familiar with COBOL...
But if this is what you want, you can set option "margin_string" to "8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72" for COBOL lexer.

yes, "margin_string".
we have 2 lexers: Cobol and Acu_Cobol, I don't recall what is the difference.

OK, thanks. How do I edit the COBOL lexer? According to the WIki I have to install SynWrite. Is that correct?

Acu-Cobol is a particular dialect of Cobol i.e. with non-standard extensions.

No SynWrite.
In CudaText main menu open "Plugins > Options Editor...", here when you check "For Lexer", changed options will only apply to the Lexer specified below.

OK, I've found margin_string but there seems no way to make a change, or in this case, to add a list of margins. I can't add changed margins to that option.

On this screenshot I have it for ini lexer.

Well I have made changes exactly as your screen shot showed but the margin lines do not show up when I open a .CBL file.

When you have file open with COBOL lexer active, open menu "Options > Settings - Lexer Specific", and check that there is a line present: If it is there, but it is still doesn't work - maybe try restarting the editor.
