If anyone wants a copy of the program, just email me.

You can also use a batch process, which is what I do. Here is what I put in a file to remove the 3 k's with primes from the n=35K-50K files:

srfile -G -d "12562406*3^n+1" sieve-sierp-base3-0M-50M-35K-50K.txt
srfile -G -d "30494864*3^n+1" t16_b3.prp
srfile -G -d "38353046*3^n+1" t16_b3.prp
copy t16_b3.prp sieve-sierp-base3-0M-50M-35K-50Kb.txt
del t16_b3.prp

Just give the file a .bat extension and run it at the command prompt.
