(See Jeff's comment at bottom)

All I meant was 'We don't see no difference at all'   We are converting
all existing numeric date field to real date fields as part of Y2K 
project.  Converting edits, and other date routines to real dates. 
As you know I use templates 'Heavily' and the process for converting
in house programs is most cases(80/20 rule) is very predictable. 

The other point is that 'We don't have 38's anymore, Buuuuuuuuuuuuuuu
uuuuutttttt,  we sure do have alot of files that were conceived on that
platform'. 

How many out there do NOT have the first AS/400 they bought since 88?????
How many out there DO HAVE files that were conceived on that box(or its
predeceasor '38,'36) 

Thats my point,  The data lives longer than any one CPU/Box.

           P.S.    (Below,)   I'll let Jeff echo my findings

           P.P.S  (Years ago when the "performance seminars" said
                  not to use "variable name calls" in RPGIII because
                  of 'poor' performance.  I still used them because
                  it was the right design technique, No performance 
                  Problems then either)
