Notice that GNU Modula-2 contains additional libraries for
input/output of @code{SHORTREAL}, @code{SHORTCARD}, @code{SHORTINT},
@code{LONGCARD}, @code{LONGINT} data types.  It also provides a
@code{RandomNumber}, @code{SimpleCipher} and @code{ClientSocket}
modules as well as low level modules which allow the IO libraries to
coexist with their PIM counterparts.
