=={{header|M4}}==

Because of the particular nature of M4, the only user-input is the code itself. Anyway the following code can be used:

<lang m4>eval(A+B)

eval(A-B)

eval(A*B)

eval(A/B)

eval(A%B)</lang>

once saved in a file, e.g. <tt>operations.m4</tt>:

<pre>m4 -DA=4 -DB=6 operations.m4</pre>

or using a sort of ''driver'':

<lang m4>define(`A', 4)dnl

define(`B', 6)dnl

include(`operations.m4')</lang>
