I cannot find anyplace to clarify this or send me in the correct direction. At the beginning of Chapters and in the TOC, it begins "Chapter 1." and needs to be "CHAPTER 1", with a double space after. My title then follows in all caps and this is happening automatically. I cannot find where the TOC command is getting "Chapter 1." in the TOC or for the Chapters themselves.

Not that advanced in knowing how to change style files, which I got from my university. But it was for EE and I am humanities trying to make it work for Turabian Style, Chicago style.

Here's the relevant portion of the utdallas.sty file. It has entries for everything but the chapters themselves, but adding the Appendix and such is there since they need the addcontentsline.

from your description of what's happening, it looks like the "Chapter" string is specified by \@chapapp, so adding this to your preamble should make it uppercase: \makeatletter\renewcommand{\@chapapp}{CHAPTER}\makeatother. some of the code for \@chapter looks rather odd though. – barbara beeton Jun 27 '12 at 20:54
@Mico -- thanks. you dug deeper than i did. – barbara beeton Jun 27 '12 at 21:14
@Mico -- only redefining \@chapapp, but not \chaptername worked for me, for what it's worth. – Ivan Kapitonov May 20 '15 at 15:12

\renewcommand\chaptername{CHAPTER}
