Btrieve and Titan - getting HEX codes out of btrieve file

I set up a DDF to read btrieve data into Delphi with Titan.  Most of the
data consists of COBOL COMP-3 fields.  The problem I have is that there
are about 350 fields in the btrieve database.  I have the DDF set up so
I have all the fields except for some COMP-3 fields that I have left
together as one big string (156 char).

Is there a way for me to specify in the DDF that I want to read the hex
code for each character in the 156 char string?  Right now Titan reads
most of the strings in as null.
