BLOCK(*YES) questions:

     FCMMASTER  IF   E           K DISK    block(*yes)

Does BLOCK(*YES) bring in a block of records in sequential order from the
file, or in keyed order?

RRN  Key
  1   AA
  2   ZZ
  3   EG
  4   BH
  5   WY
  6   WZ
  7   AB

In this scenario, will the block of records be in RRN sequence or in keyed
sequence?

RPG documentation is not, IMO, not very helpful in indicating how blocking
occurs.

The archives has a post that appears to support a block "by keyed records":

I have found several posts that imply that blocking is by physical sequence. 
But nothing that says this. 

Is there an IBM reference to this?

TIA,
Dan
