I am trying to get a prime of a form not expressible using pfgw's parser into
the top-5000.

Given that the smallest top-5000 prime is now 63893 digits, the 60K limit seems
a particularly unfortunate restriction - and the sort that PFGW doesn't normally
have.
Why can't it be some much less stringent limit like (e.g.) 1000K?

I think such techniques of running 1000's of batch files might possibly lead to
even longer PRP'ing times than forgoing the
// -f{}
construct altogether.
