RE: Two reade loops: which one preferred ?

["Booth Martin" <Booth@xxxxxxxxxxxx>]

Having learned most of my style from Jon, I agree with Jon's comments. 

However may I tilt the topic slightly?   Yes, reade is a useful tool but did
anyone ever do any benchmarking of reade vs read with BLOCK(*YES)?

 >> So, applying the C/PASCAL approach to RPG forces to include one
additional read before the loop as in Style#1.
 
I always code the additional read before the loop - but for very
straightforward logical reasons that have nothing to do with choice of
language.
 
If the very first read of a file causes EOF, then that (in most cases) will
be an _error_ condition.  On the other hand, EOF within the loop is an
_expected_ condition - or I'll never get out!
 
I simply prefer to handle those widely different circumstances with two
separate reads.
