 Sorry, I was away on a business trip.

There is a save/restore facility (see the Jenks book, volume 0 at

You cannot interrupt a long running computation, save it, and then
restore it and continue. Break the computation in parts and do
save/restore at the parts. You could write an input file to do
checkpoint saves after each part completes.

Hello, Tim!

What I meant by saving the intermediate results was what you said: break the computation in multiple input files and save at the end of them and load at the begining.

I tried using the )history commands, but it isn't working. I am using OpenAxiom-1.3.0 on Windows, and when I issue a command like ")history )save test", axiom returns me

>> System.error:
#p"test.input" is not a type of STRING.

I don't know how to fix it.
Thanks a lot!
