  Steps to reproduce:
  
  1) Create a program with the following code which works in v6 an
  d doesn't give any error in v71 neither on the EGL Editor nor th
  e Problems view:
  
  package test;
  
  // basic program
  //
  Record MYREC type BasicRecord
          co_domaine_id char(3);
  end
  
  program Test type BasicProgram {}
  
          function main()
                  ai_rec_dl_inscriptions_bzi MYREC;
                  ai_rec_dl_inscriptions_bzi.co_domaine_id='002';
                  SysLib.writeStdout('id='+ai_rec_dl_inscriptions_
  bzi.co_domaine_id);
                  if (ai_rec_dl_inscriptions_bzi.co_domaine_id in
  ['001', '002', '003', '004', '006', '007', '008', '009', '011',
  '101', '102'])
                          SysLib.writeStdout('match');
                  else
                          SysLib.writeStdout('doesn't match');
                  end
          end
  
  end
  
  2) Generate the Java code
  

Local fix
