That tells PFGW that it should stop searching a particular $a value (that is, the k) if 1 prime is found for that value.

pfgw -l name-of-sieve-file.txt
this call will test the file for PRP's, and it won't stop on finding a PRP!

i've tested this with the Sierp Base 3 file with the header
ABC $a*3^$b+1 // {number_primes,$a,1}
i tried $a or $b, the same.

WinPFGW won't stop!
