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).
