I'd be willing to bet that it is not 'down in the bowels of the system'.
I think it may be 'at the top of the system'

By that I mean,  Down in the bowels I think CREATE TABLE equates/runs
the CRTPF CPP.   I think it may be the fact that there is not a 
MBR parameter on the CREATE  TABLE SQL command. 

Try creating a table with SQL and then go ahead an do a CHGPF and 
change it to MAXMBRS(*NOMAX)  and add a couple of members.  I 
bet you can.  I don't know for sure, I haven't got my machine on
at this moment.  

The other major differences is that the CREATE TABLE creates a 
journal receiver automatically and a few other thing I think.
