Field contents by reference?

I have two files: The first is a data base file, XXX, with many date 
fields. I would like to validate the contents of each specific date fields. 
The second file is an output file, XXXFIELDS, from a query over a file 
generated from DSPFFD. File XXXFIELDS has only four fields (file name, 
library, field name, field text). The query selects specific date fields to 
analyze. So, I would have XXX/Lib/Fld1/text; XXX/Lib/Fld2/text…..etc.
Since there will be several files to analyze - each with several date 
fields - I wanted a more generic program with as little hardcoding as 
possible. The intent was to read a record from XXX then get all of the date 
field names from XXXFIELDS retrieving and analyzing the contents of each 
date field before going on to the next XXX record.
Is there a way to get the contents of the date field using the field name 
retrieved from XXXFIELDS. There must be a way to reference the data. 
Pointers? %ADDR?
Thanks again for your help.
