I have commented offlist with Mike about this.

Yes, the 1.2 version has a 60000 char limit for ABC files (the dev version kicks
this up a little). Also, in the "sample", Mike set his $a value to a negative
number. This causes the modular sieve to NOT give proper results. That
negative sign must also be removed to get things to work (in the ABC file).


NOTE that if used like Jens stated, then pfgw can be called, and the modular
factoring string can be provided on the command line (in the -f switch).
