RE: Data manipulation

I have done code similar in the past in different languages.
Here is what I did in pseudo code:
1) Trim the input getting rid of extra spaces on the beginning and the end.
   If the length of the resulting string is 0, throw this record as an exception
2) get the position of the last space in the field
   Move the field into a holding variable
   Do while scan position is not 0
     Scan for space.  If not 0 Grab text from this position to end of file as 
holding variable
3) We should now have the zip code in our holding variable.
   Try to validate it.  It should be in 9999 format or 9999-9999 format.  If 
not, throw this
   record as an exception.  It could be a Canadian postal code, or European or 
some other country.
