Paul,

My first gut reaction is that you are out of luck.

It appears that your data base has violated rule #1 of normalization and has a
composite field.  IMO it's easier to concatenate than it is to parse.  Had the
file been defined differently the 3 numeric positions would have been a separate
field.  After all they do appear to have some intrinsic meaning or validity 
rules
and should have been defined accordingly.

Sorry :(
