I think you meant:

unsigned char    symbolChar;

Can we then in the initWithChar method just use:

symbolChar = aChar;  ?

OK, here we go :)

I am now looking into updating the translation code. This is not my  
field, so I hope I do it right, and therefore ask here before I  
really screw up.

1. Should we keep the BCSequenceCodon subclass?

2. The translation code now uses symbolArrays. Should we keep this,  
or do we need to rewrite these classes so that they use the char  
array in NSData?

I rather not commit them to CVS until the classes are more finalized.  
But if no-one objects, I will commit the updated files. Or I can use  
a CVS branch. Anyone knows how to use branches within Xcode?
