23.2 Upper and lower case

Synopsis:

\uppercase{text}
\lowercase{text}
\MakeUppercase{text}
\MakeLowercase{text}

Change the case of characters. The TeX primitives commands \uppercase and \lowercase only work for American characters. The LaTeX commands \MakeUppercase and \MakeLowercase commands also change characters accessed by commands such as \ae or \aa. The commands \MakeUppercase and \MakeLowercase are robust but they have moving arguments (see \protect).

These commands do not change the case of letters used in the name of a command within text. But they do change the case of every other Latin letter inside the argument text. Thus, \MakeUppercase{Let $y=f(x)$} produces ‘LET Y=F(X)’. Another example is that the name of an environment will be changed, so that \MakeUppercase{\begin{tabular} ... \end{tabular}} will produce an error because the first half is changed to \begin{TABULAR}.

LaTeX uses the same fixed table for changing case throughout a document, The table used is designed for the font encoding T1; this works well with the standard TeX fonts for all Latin alphabets but will cause problems when using other alphabets.

To change the case of text that results from a macro inside text you need to do expansion. Here the \Schoolname produces ‘COLLEGE OF MATHEMATICS’.

\newcommand{\schoolname}{College of Mathematics}
\newcommand{\Schoolname}{\expandafter\MakeUppercase
                           \expandafter{\schoolname}}

The textcase package brings some of the missing feature of the standard LaTeX commands \MakeUppercase and \MakeLowerCase.

To uppercase only the first letter of words, you can use the package mfirstuc.
