RE: int vs binary questions

["Steve Richter" <srichter@xxxxxxxxxxxxx>]

I have a 170 with 460 cpw.  But that should not matter, all the results are
relative to the same system.  Bin to bin is 15% faster than int to int.  Add
to bin is off the charts, 20x slower than add to int.

I would like to know if the rpg definition of "Binary" is unique to it and
if it predates the s/38.   And was the as400 database handling of binary
something forced on it by RPG?

   Gosh I hope those are resource related performance results and not true
   results. If that is true, then IBM implemented INT variables in RPG
poorly
   and should fix it and PTF it back to V1R1.

     is there a dds equivalent to "10i 0"?

     I ran a timing loop that copied between 10i 0 and 9b 0 variables. here
     are
     the results:
      bin to bin was the fastest.
      int to int was 10% slower than bin to bin.
      bin to int took twice as long as bin to bin.

     any idea why bin to bin runs faster than int to int?

     The practical side of this is that I have gotten into the practice of
     declaring all integer type variables as 10i 0. But when I have to store
     such
     a field in a database file, I dont know the best way to declare the
     database
     field.
