Actually, there *is* a difference in the created file.  I didn't believe that
an SQL file was any different from a DDS file until I tried this:

create table test (key numeric(5,0),name char(30))
chgpf test maxmbrs(2)

It bombs and tells me that I can't change an SQL table to be multiple
members (at least it does on V4)... CPD3213...
  SQL tables, views, indexes, and non-SQL files that are in an SQL data base
must have only one member; however, the value that you specified on the     
maximum number of members (MAXMBRS) parameter is either a number greater    
than one or *NOMAX.  For more information about SQL tables, views and       
indexes, see the Programming: Structured Query Language Programmer's Guide, 
SC41-9609.
