RE: RPG Indicators

[Tom.Clements@xxxxxxxxxxxxxxx]

This structure seems inefficient to me, though I've seen it quite a bit.

For every read, you check twice for EOF? Why?

My preference is to just have one file input operation for the loop, i.e.:

     c     Key           Setll     FileName
     c                   DoU       %EoF( FileName )
     c     Key           ReadE     FileName
     c                   If        not %EoF( FileName )
      ***   do stuff
     c                   EndIf
     c                   EndDo

This has always worked for me.
