Hi Wayne!  I believe it's been like that since V1R3.  I suppose any
feature of the language could be a source of logic errors if not used
properly.  READE was "enhanced" to improve performance in certain cases.

BTW, in the next release of RPG, all indicators on I/O operations will
now be optional!  You'll be able to use built-in functions to test end of
file, record not found, etc.

Cheers!  Hans
