Re: CHGPF and CHGLF

I have used the CHGPF command with LVLCHK(*NO) and a source member to
add fields to the end of the record format on-the-fly.  Then after
recompiling all the programs that touch the file, I change it back to
LVLCHK(*YES).  But I've never done it on a file with LFs built over it.

Now I want to do this to a PF that has logicals over it and I'm
apprehensive.  The CHGLF command does not have SRCFILE and SRCMBR parms.
 Will the following work:

1) CHGLF LVLCHK(*NO) on all logicals.
2) Change the PF source member (and LF ones if applicable).
3) CHGPF with LVLCHK(*NO) and SRCFILE/SRCMBR.
4) CRTLF from source member with LVLCHK(*NO) for all logicals.
5) Compile all programs touching the PF or any LF.
6) CHGPF LVLCHK(*YES)
7) CHGLF LVLCHK(*YES) on all logicals.

Unless you need to make changes to the logical records themselves, there's
no need to recompile logicals.  The CHGPF command will take care of
dropping and recreating them. It will even take care of constraints and
triggers for you.
