[LON-CAPA-users] catching maxima errors

[Gerd Kortemeyer]

Hi,

If you get "code ran too long" it's likely because the connection to MAXIMA times out. Does the problem work otherwise, meaning, can you get it right and wrong? If those also don't work, you should try restarting "loncontrol"

If "CORRECT" and "INCORRECT" both work: is MAXIMA somehow running in German? What does it say when you enter your expression from the command line?

- Gerd.
