<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<i>Factor</i> prints <i>number</i> and its prime factors, each repeated the
proper number of times. The number must be positive and less than
254 (about 1.8&#215;1016).
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
If no <i>number</i> is given, <i>factor</i> reads a stream of numbers from the
standard input and factors them. It exits on any input not a positive
integer. Maximum running time is proportional to <i>-/n </i>.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
<i>Primes</i> prints the prime numbers ranging from <i>start</i> to <i>finish</i>,
where <i>start</i> and <i>finish</i> are positive numbers less than 256. If
<i>finish</i> is missing, <i>primes</i> prints without end; if <i>start</i> is missing,
it reads the starting number from the standard input.<br>
