Hello All,

Yes, the material below was discussed a long time ago, but at that time I did not follow what was going on, but kept the message thinking that some day in the future it would be of interest. Well . . . that day is here!  ;-)

I don't follow Alan's comment "Make sure it's after the \counterwithout command." because on commenting out the \counterwithout command, Alan's code typeset as George wanted. Also, on commenting out the line <\usepackage{chngcntr}> as well, the typeset was correct!!!

However, since George wants chapters numbered as I, II, III, . . .  I used the following preamble to obtain the desired form:


Could not find anything about \counterwithout nor \usepackage{chngcntr} in The LaTeX Companion nor did the bash shell turn up anything via $texdoc .... However, on commenting out the \usepackage{chngcntr} line but leaving \counterwithout intact, the error message was that "\counterwithout was an undefined control sequence" which makes sense.

I have this uncomfortable feeling that, once again, I'm missing something!
