O, I see what you mean:
llRetry = 0
lcFile  = MyGetFileRoutine()
DO WHILE llRetry < 3 && We don't want to loop endlessly here :-)
   TRY
         some code
         USE (lcFile)
  *      more code
         llRetry = 700
   CATCH WHEN 3 && Can not open the file
         lcFile = MyGetAlternateFileRoutine()
         llRetry = llRetry + 1
   CATCH
        *** do the normal CATCH programming
        llRetry = 700
   ENDTRY
ENDDO
