Jumps and yyin

[Bruno Ribeiro]

Hello!

I'm trying to implement jump operation, like GOTO, on my visual basic 
interpreter. What I have done was index all the line numbers as file 
positions. So when I do a jump operation, all I have to do is a fseek to 
the new file position. But fseek is shifting yyin to strange positions, 
I don't know why.

Does anybody knows something about that?

Thanks,
Bruno.
