Ya,  after I wrote the "I stand corrected" message I thought about it 
some more.  And I remember the attribute on the DSPFD that you just 
posted.    I now go back to my earler position that a SQL CREATE DOES do
a CRTPF under the covers and that an SQL table is like any other
Physical file structure.   The only difference I believe is in the 
File Control Block(FCB) or the Object header, etc.  the flag that says
this file was created using the SQL CREATE command (SQL FILE TYPE as 
you listed.)    The CHGPF CPP looks at this attribute(flag) and says
NO, YOU CAN'T DO THAT.  

BTW  you did a DSPFD right?   not a DSPSQLTBL command right????? <G>
