That all depends what direction you are going. It is ALWAYS best to  
post a short code example because that will answer all sorts of  
questions.  For now we'll have to assume you are:

1) Not using Carbon Events
2) Converting the nib fields to FB buttons  since you are apparently  
successfully using def SetButtonTextString.
3) fn ButtonTextString$  retrieves a string given the button number.

Using def SetButtonTextString. and fn ButtonTextString$ are fine if  
your needs are limited to 255 characters or less.
