Here's a simple RPGIV program that will update records according to the
conditions you've described.
The things you need to know are the file name and it's record format name.
The nasty part is getting all of the entries on the F spec right if you're
unfamiliar with RPG.  If the file is large (several million records) it may
take a few minutes to run.  This is the brute force approach--read all the
records and change the ones that meet the criterion.

Some others on the list have suggested SQL.  I'd probably do it that way
too, to tell the truth, but this will work and the source is not too much
longer than the update query that would do the same thing.

 Fyourfile  uf   e             disk                               
 F                                                                
 C                   read      rcdfmtname                         
 C                   dow       NOT %eof(yourfile)                 
 C                   if        dtype = 'JRNL' AND ddstat = 'A'    
 C                   eval      ddstat = 'X'                       
 C                   update    rcdfmtname                         
 C                   endif                                        
 C                   read      rcdfmtname                         
 C                   enddo                                        
 C                   eval      *inlr = *on

> Both JRNL and 'A' need to be true then, change the 'A' to an 'X'.
