Re: adding new fields to PF

[Jeff Crosby <jlcrosby@xxxxxxxxxxxxxxxx>]

You are essentially correct and I have done this to production files.

In the 10,000' view, this is what I did:

1) Add the fields to the DDS.
2) Do a CHGPF FILE(lib/file) SRCFILE(QDDSSRC) SRCMBR(*FILE) 
LVLCHK(*NO).  The file now has the new fields.
3) Recompile your RPG programs.
4) Do a CHGPF FILE(lib/file) LVLCHK(*YES)
5) Now start doing whatever programming needs done to actually use these 
fields.

Note that the above assumes you're using DDS to define the files.  I 
have switched to all DDL.  I have not added fields to a file since the 
switch to DDL, but the steps would be similar.  No CHGPF, but ALTER 
TABLE statements instead.

Note that LVLCHK(*NO) on the production file was only for the short time 
(minutes usually) needed to recompile the affected RPG programs.
