APL is still heavily used by insurance companies to calculate their
non-standard insurances for large companies, where the normal routines
won't work due to special conditions etc.
APL development is very fast compared to other (compiled) languages.
I don't do it myself, but I am told so by lots
In the 70's three companies based their businesses on APL-based time
sharing services: Scientific Computing (Wash. DC), SECOS (Poughkeepsie)
and another in Toronto and it was popular in universities. For a time
before networking as we know it today existed, that was pretty impressive.

Hi everyone,
My company is willing to deploy a project under Linux S/390. Weve got a Multiprise
3000 and are looking ahead for a SuSe Enterprise Server 8.0, but providers (Novell)
have sent an offer around 5.400 .
It seems to be a little expensive, is these the real cost of the Enterprise
Last I checked (which has been a while), the euro was running pretty
close to the dollar, so the price is probably right.
If you really want to provide official support for SUSE, you may need to
just do it. There are a few free alternatives available now that look
quite good. But it's a pretty

Just thought i would ask to see if there are any tools out there for this.

I do not run a very complicated linux subsystem, but I do use a shared
read-only /usr minidisk. This one disk is 2500 cylinders and is shared by 3
production machines. My simple savings is 5000 cylinders, but the basic
calculation for savings would be
(Nservers - 1) * 2500 = total cylinders saved

From what I can tell, the current list price of SLES8 on a Multiprise is

good deal.

Nothing that will convert in-place. If you just want a journaling file

We tried making /usr a ro minidisk. It did not work for us. When we had

My setup is quite simplistic. ALL servers are running the same kernel and

Yeah, J is pretty cool. Beats Matlab up one side and down the other.
