-encode- maps string variables to numeric
variables 1 to #distinct values, in alphanumeric
order. 

Thus 

	euphemism 
	barbecue
	aardvark 
	aardvark 
	concertina 
	deluge 

will get mapped 

	aardvark      ->         1
	barbecue      ->         2
	concertina    ->         3
	deluge        ->         4 
      euphemism     ->         5 

and the strings on the left become 
value labels for values on the right. 

That's it, more or less; evidently less
than you expected.
