programming the prime

[leprechaun]

Hello to the forums!

I am relatively new to the prime and somehow stuck in the learning process. As a result it is likely that I will post several dumb or silly questions in the future.
I hope you can help me with the machine....

Based on some tutorials I tried the following

Code:


EXPORT fircore(N)
BEGIN
  LOCAL core:=seq(0,N);
END;

Codecheck complains: Syntax Error.

Code:


EXPORT fircore(N)
BEGIN
  LOCAL core:=seq(0,10);
END;

That would work.... Can you explain the issue and give startup tips to master the machine some day?

Thanks
