I once came across a piece of C code that looked something like this (small
section only shown):

IF (JRXBBB NE JKLFUEL) THEN
   RRXFLOWR = 1.0;
ELSE
   RRXFLOWR = 2.0;
ENDIF;

etc. Basically, the person who wrote it had used FORTRAN for many years and
when required to use C, decided he hated it so created masses of macros that
allowed him to write C code with an (almost) FORTRAN syntax.

While this is an extreme case, such (mis)use of macros in languages such as
C is common and this is why I approve of languages like Ada that supply no
macro facility. What you see in a piece of Ada code is what you get (within
a debugger for example). This does not hold true for C or other macro languages.
