Martin, The lot of bogus expressions in mapleok seem only to occur in the fricas version. They have long since been fixed in Axiom. If you know of more errors please let me know. There are two integral test suites, one based on Bondarenko's published Maple failures and the other based on

Your initial report showed the problem from Open-Axiom which is not the Axiom project. What command line did you use to start Open-Axiom? Your problem is also in Axiom so it is listed as a valid bug report. It has been assigned bug number 7198. Tim Arnold Doray wrote: This problem persists in

The directory $AXIOM/input contains a large number of files which can be read into Axiom and executed. There are examples of quite a few domains. 5) HYPERDOC Clearly you cannot get hyperdoc running. I am not sure what the problem might be but if you send me email we can discuss it further. Tim Daly

Axiom does use C code as part of its implementation and there are ways to link the C code so it is possible. Is there a reason you need to write in C? What is it you are trying to do? Tim £ukasz wrote: Hi. I want to ask if its possibe to write some finction in C and aply it in AXjOM ( its
