Frank,

You can try this:


      * Redefine the field names from your file as a data structure
     D MonthsDS        DS
     D  MONTH01
     D  MONTH02
     D  MONTH03
     D  MONTH04
     D  MONTH05
     D  MONTH06
     D  MONTH07
     D  MONTH08
     D  MONTH09
     D  MONTH10
     D  MONTH11
     D  MONTH12
      *
      * Then define an array that overlays the data structure
     D  MthsAry                            Like(MONTH01) Dim(12)
     D                                     Overlay( MonthsDS )
      *
      *
      * Now you can access each field as an array element, or by name
     C                   Eval      MONTH01    = 1
     C                   Eval      MthsAry(1) = 1
