Just for completeness, this pure perl version should also work: 

{
    my $seed;
    sub ppSrand{ $seed = int( $_[ 0 ] & 32767 ); }
    sub ppRand{
        my $max = shift // 1;
        $seed = ( $seed * 214013 + 2531011 );
        return ( ( $seed >> 16 ) & 32767 ) / 32768 * $max;    ## Amend
+ed per post below.
    }
}

ppSrand( 555 );
print int ppRand( 1000 );
