  20
  21    <p>Although programming languages generally have common aspects, they are
  22 rarely expressed in the same manner.  For instance, in ANSI C,
  23 dereferencing a pointer <code>p</code> is accomplished by <code>*p</code>, but in
  24 Modula-2, it is accomplished by <code>p^</code>.  Values can also be
  25 represented (and displayed) differently.  Hex numbers in C appear as
  26 <code>0x1ae</code>, while in Modula-2 they appear as <code>1AEH</code>.
  27
  28    <p>Language-specific information is built into GDB for some languages,
  29 allowing you to express operations like the above in your program's
  30 native language, and allowing GDB to output values in a manner
  31 consistent with the syntax of your program's native language.  The
  32 language you use to build expressions is called the <dfn>working
  33 language</dfn>.
