No, the message says: "GREP is invalid as a function". This
means that OPQUERY was trying to call a Lisp *function*
whose name is GREP. This has nothing directly to do with the
unix grep utility -- except that it does: We know from other
discussions about Axiom on Windows that the Lisp function
GREP was one of those things that was re-written by NAG as
a C extension of CCL when they ported Axiom to Windows.
On Linux the GREP function just calls OBEY "grep ..." which
uses SI::SYSTEM to call the grep utility, but (usually) this is
not possible on Windows so they wrote it in C. But this was
not back-ported to GCL when GCL was used to implement
Axiom on Windows.
It is possible that including some "grep-like" command on
Windows *might* work if you also disable the "Saturn" option.
This might re-enable the Linux-compatible GREP function
which would then call your fake grep utility much like on linux.
As I recall there were some other reasons why Saturn should
be disabled on windows - check the axiom-developer email list
for how to do that.
Otherwise, if that doesn't work, you might have to provide such
a GREP function yourself (just copy from the Axiom source).
