Here are a few more options to explore:

- select ODBCConstants, choose explain from the shifted context menu.  
For TextConstants, I get

TextConstants "is a global variable.  It is a pool which is used by  
the following classes (CharacterBlock CharacterScanner  
MultiTextComposer Paragraph MultiNewParagraph CompositionScanner Text  
LimitingLineStreamWrapper TextLineInterval MultiCharacterScanner  
TextStyle StrikeFont HostFont DisplayText SegmentScanner CharRecog  
ParagraphEditor)"

- press delete, select ODBCConstants again, and press Cmd-Shift-N (or  
choose "references to it" from the shifted context menu). This will  
show you a list of methods that directly reference the dictionary.  
One of them surely is the defining method.

About actually changing this to a SharedPool ... you probably should  
leave that to someone actually knowing what he's doing ;-) Basically  
you create the new class, add all the pool vars as class vars, write  
an initialize method to assign the values. By using the same name all  
references should automatically be correct - if not, you would have  
to change them by hand.


OTOH, it might be a lot less trouble to just add your constants to  
the existing pool in a class initialize method.
