Thank you for your remarks. Too bad they fell into my acres of ignorance.
One thing is certain, Dawson used brackets [] not parens (). When I 
spoke of typi (plural of typo) I meant ; for : or \ for /, not line 
after line of error.
My only alternative now seems to be 'get out the old curry comb' and go 
letter by letter, between the monitor and the page. Headache time.
