<DIV>"Is it possible to generate any 'mixed' *plain* courses, i.e., including 2nd <BR>and 8ths place methods without using any calls? (I don't think so, but would <BR>be glad of a proof if any - especially a counter example.)"</DIV>
<DIV> </DIV>
<DIV>If, say, 14263857 is produced by a plain lead, then so must 12345678. Therefore, so</DIV>
<DIV>must 13527486. Therefore, so must 15738264. You get the gist. </DIV>
<DIV> </DIV>
<DIV>Hence it is not possible. The same argument works for 2nds place lead ends.</DIV>
