Thanks for the tips :-)

The number 1-with-ten-zeros-after-it can be written as 10 ** 10.

Thanks! That's what I was looking for there. Yup, the eval(1 . '0' x 10) was a hack.

This invokes "last" before "print" -- meaning that the print never gets invoked. You probably want print <<__FOUND__ and last PRIMESCAN.

Yes, quite. Thanks.
