OK. I see that now.

I'll redo the mistake and look in the .log file.

The syntax that the LaTeX Companion uses does not present the first argument in the {...} form. Hence my query about that. I had to reread Graetzer before realizing the two argument requirement.

Thanks for your clear explanations. 


After reading more stuff in The LaTeX Companion, I think the following may be an answer to my original question:

In The LaTeX Companion there are several instances where the authors write

\commandname\cmndname{...argument...}

which is a short form of

\commandname{\cmndname}{...argument...}

I suspect they use the above consistently ;-) but I was not sure of that when I penned my original message.
