I need to appologize, the first few lines of my thread didn't print, so let
me enter my question again.

I have a record with three fields; Serial Number, First Name, Last Name

Serial Number     First Name     Last Name
  DR0001             Darrell            Roak

My rule for the Serial Number is:

<first letter of First Name> <first letter of Last Name> <next sequential
number>

I would like to automate the Serial Number by extracting the first
characters of the First Name & and Last Name fields and concatenating them
with the next sequential number.

Is there a function defined for this or do I have to write a few lines of
code? If code needs to be written, could you help me a bit.
