RE: Using a Data Area in CMD Statements

["Doug Cosgrove" <dcosgrove@xxxxxxxxxx>]

Ted,

Check out the EDTDTAARA utility on the NEWS/400 site. It displays the data
in the data area and updates the data area with your changes. The data is
not formatted it is just one long string. This may be a good place to
start. It has a limitation of only displaying/changing up to 450 characters
but I modified it to display 1024 with little trouble.

Yes, but it has nothing to do with DTAARA(*YES).

As Mike said, you need a prompt override program to load the value at
prompting.  Your command processing program would need to save the last
value passed.

I think you would also need a default special value for when the command is
not prompted which would tell the command processing program to go out to
the data area to get the value to use (generally *SAME).  I thought I had a
command that used prompting where I could check this, but I couldn't find
one.  I think it was actually at a previous job.

You can find more about prompt override programs in the CL Programming
manual.  For V4R4 see:
