<hr>
An <i>expression statement</i> is any
<a href=208.htm>expression</a> followed by a
<a href=151.htm>semicolon</a>.
<p>
An expression statement is executed by evaluating the expression.
All side effects of this evaluation are completed before the next
<a href=215.htm>statement</a> is executed.
Most expression statements are
<a href=210.htm>assignments</a> or
<a href=214.htm>function calls</a>.
<p>
A special case is the <i>empty statement</i>, consisting of only a
<a href=151.htm>semicolon</a>.
An empty statement does nothing, but it may be useful in situations
where the ULP syntax expects a statement but your program does not
need one.
