Hi Maike,
Have you heard of sagetex? This allows sage computations as part of the
compilation of a latex file. From my experience, this is not very good
for interactive work because all the code within the latex file is
compiled every time you run sage over your document, but it's great for

For various objects and various software systems (like mathematica,
magma, maxima, etc.), we have a _mathematica_init_, _magma_init_, etc,
which convert an expression into syntax for the target system. A lot of
these are defined in calculus.py for converting symbolic expressions to
syntax
Hi William,
That sounds great to me. As long as it'll allow me to load the ngerman
package in the notebook version of Sage, that'll do. Thanks!

P.S. And thanks Stan for the hint! I didn't know sagetex. As I'm using
the notebook to combine latex typesetting with the interact
functionality

Let me get this straight. Please correct me if I am wrong.
You sarted GAP within Sage (using sage -gap?) and then
started a long computation, whcih caused you to run out of memory.
Then GAP and Sage froze, so you rebooted and restarted Sage.
(Since you rebooted, I guess you are using windows?)

Hi Geir,
If you really want to use strings, it may work like that:

sage: EqL=['y==x**%d-%d'%(i,i) for i in range(10)]
