Phil,When you change the DDS source for a PF, and then use CHGPF referencing the updated source member, it will update the file to use the changes in the DDS.
So if you edit the DDS and add a field, you can use CHGPF, and it'll add the field to the file.
AFIAK, using CHGPF this way is nearly identical to renaming the file, creating a new one with CRTPF and copying the data back. If there's a performance difference between the methods, I doubt that it's significant. The bigger problem is recompiling all of the programs that use teh external definition, and the time that that'll take.

Yes but I don't see how you can add a field to the file using CHGPF.
