Digital BW, The Print

Thanks Paul, most of what you said I know, some I didn't...after 
reading your post, I dragged a CAnon RAW file to CS2 and it opened  
up in the RAW converter. When it is in that converter I am limited 
to what only can be done in that converter itself, not in CS2
(editing program. I then have to convert it to something else, which 
I always do TIFF before I edit it. 
  So my question still stands to Shoshanna's post, which I still 
don't understand, which is below this post. 

Shoshann wrote<<< Another important plus-- at least for many of us-- 
is that a RAW file can be successfully enlarged to considerably 
greater 
dimensions, while maintaining considerably greater quality, than can 
a JPG file. The image has far more data with which to work, and it 
shows.>>>>>>>>>>>>>>>>

I questioned.
   I was under the 
 impression that RAW files can't be printed as a RAW file, but 
 must be translated to another type of file. I admit I have 
tons of holes in my PS and digital knowledge and I  heard or read 
this and believed it.  Ques is.............. 
 How does one enlarge directly from a RAW file?....OR, am I 
 confusing, enlarging with printing.
 THanks again,
Frank
