'help.vim' syntax file, example string to match 'helpHeadline' element

Question

I am playing with vim syntax files and using help.vim as a guide to create my own syntax file. Changes I make in my syntax file are correctly applied in a test file but my problem is with creating a string to match helpHeadline; it's definition is:

syn match helpHeadline "^[-A-Z .][-A-Z0-9 .()]*[ \t]\+\*"me=e-1

Can anyone give me an example string that would match it please.

Answer 1

The comment from @hwnd helped me to find the answer myself.

An example string would be:

ABC *

Note the text at the end of the regular expression me=e-1 is not part of the regular expression but is a vim script statement used in syntax files.
