Parsing the Form ID Security report

Hi,

I am new to Lawson and I'm in the process of writing a script to parse the Form ID Security Report. I'm wondering if anyone has a listing of all the possible values for the "Unsecured FCs" column as well as a definition of what they mean? No one in accounting (who's been managing the system) knows or knows where to look and I'm trying to have IT take over administration of this. 

Example:

                   SYSTEM   PROGRAM                     UNSECURED             SECURED
  PRODUCT LINE     CODE     CODE     FORM ID   SECURED  FCs                   FCs
 -------------------------------------------------------------------------------------------------
  PRODUCTION        AB      ABSR      ABSR.1     NO     I
  PRODUCTION        AC      AC00      AC00.1     NO     ACDINP
  PRODUCTION        AC      AC00      AC00.2     NO     ACDINP+-
  PRODUCTION        AC      AC00      AC00.3     NO     CINP
  PRODUCTION        AC      AC01      AC01.1     NO     ACDINPMVFZRU-+

What do all the letters under the column equate to? I know some of them, but I was wondering if there is anything that will define all of them for my reference as I write this script.
