Hi Joe

We pretty much all used this method in our department, and got a bit
confused with the right %BIF to use when moving to RPGIV. We settled on
a one line extension to it and just used the (functional equivalent)
SETLL/READE pair instead of the CHAIN and just use %EOF.

 FileKey  SETLL    File
 FileKey  READE    File
          DOW      not %EOF(File)
         (process)
 FileKey  READE    File
          ENDDO
