>&#13;    Often you'd want to execute a statement if a certain condition is
    met, and a different statement if the condition is not met.  This
    is what <TT
CLASS="literal"
>else</TT
> is for.  <TT
CLASS="literal"
>else</TT
>
    extends an <TT
CLASS="literal"
>if</TT
> statement to execute a statement
    in case the expression in the <TT
CLASS="literal"
>if</TT
> statement
    evaluates to <TT
CLASS="constant"
><B
>FALSE</B
></TT
>.  For example, the following
    code would display <TT
CLASS="computeroutput"
>a is bigger than
    b</TT
> if <TT
CLASS="replaceable"
><I
>$a</I
></TT
> is bigger than
    <TT
CLASS="replaceable"
><I
>$b</I
></TT
>, and <TT
CLASS="computeroutput"
>a is NOT bigger
    than b</TT
> otherwise:

    The <TT
CLASS="literal"
>else</TT
> statement is only executed if the
    <TT
CLASS="literal"
>if</TT
> expression evaluated to
    <TT
CLASS="constant"
><B
>FALSE</B
></TT
>, and if there were any
    <TT
CLASS="literal"
>elseif</TT
> expressions - only if they evaluated to
    <TT
CLASS="constant"
><B
>FALSE</B
></TT
> as well (see <A
HREF="control-structures.elseif.html"
>elseif</A
>).
