Hi Aaron,

No need for the Do and Iters. This is a straight Select Group.

     C                   CLEAR     *ALL          RCSTMST
      *
     C                   Select
     C                   When      (BSi = 0)
     C                   eval      WSTEXT = 'Bill-To information is required' +
     C                                      'for new customer.'
     C                   EXSR      $Error
      *
     C                   When      (BSBZP(1) = ' ')
     C                   eval      WSTEXT = 'Bill-To information is ' +
