 Gene thanks for the synopsis of the SOUNDEX algorithm and your 
 comments. 
 GL> I used to use SOUNDEX code to retrieve entries in a database. 
 GL> Using SOUNDEX made the program very tolerant of spelling errors. 
 GL> I seem to recall that certain database programs had this function 
 GL> built in. 

 This is exactly what I had in mind.  i.e. Using the SOUNDEX code as the 
 index into the list of names, and then displaying appropriate names for 
 selection by the User in an alphabetic listing.  Hoping that this 
 would be tolerant of spelling errors.  However, with the experimental 
 run I have done and the range of names that may have the same codes I 
 am wondering what to do? 

 For example: 
         Code B200 includes: BAUGH, BEGGS, BOSSE, BOYCE, BUKSH 
         Code B520 includes: BAINS, BANJI, BINGA 
         Code K400 includes: KALE, KELLY, KUHL, KYLE 

 Now if every name in the range is displayed, little if anything is 
 gained.  Should the selection only display the other names with 
 matching codes, Ignoring others with spelling that may be 
 alphabetically adjacent?  Or ... 

 I have experience with using a straight string comparison but would 
 like to find something that might provide additional tolerance. 

 Thanks for your comments.  Zafar.
