Re: BLOCK(*YES) questions

[Dan <dbcerpg@xxxxxxxxx>]

Yes, the file is defined as keyed.  To clarify the example scenario, let me
add that RRN 950 in my sample file has key 'AC'.  You are suggesting that the
block of records as shown in RRN order in my original post would appear to the
program in a block that looks like this:

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

Did I read your statement correctly?  Does IBM clarify this at all?  If I
wanted to test this, would an RPG DUMP show the number of blocks read, or
would I see it somewher in the file's INFDS?
