Looking for HIDDEN and PROTECTED modifiers, as well as the truncated forms of the keywords, is a very nice touch, Thierry. Well done.

A different approach for the pattern that looks for PROCEDURE, but following your lead on those two aspects:

m.RegEx.Pattern = "^\s*(((hidd(e(n)?)?)|(prot(e(c(t(e(d)?)?)?)?)?))\s+)?(proc(e(d(u(r(e)?)?)?)?)?)\s"
