Re: Retieve source from Display File

It is also possible to see the layout in PDM - WRKOBJPDM to the library where it resides, find the DSPF, take a 5 option, then use the various options for the formats and all. If you have done a DSPFFD first as Mark suggests, you have a chance of understanding which indicators might control subfiles, etc. This is still not going to get you everything, like SFLMSG or ERRMSG, seems to me. Gotta use the API for that.

Hi, Tom:

Run:
DSPFD FILE(*ALL/*ALL) TYPE(*MBRLIST) OUTPUT(*OUTFILE) FILEATR(*PF)
OUTFILE(QGPL/ALLMBRS)

(submit this as a batch job as it may run for quite a while.)

Then use SQL or Query/400 etc. to search this file to see if you can
find any members in any other libraries with the same name -- perhaps
you might get "lucky" and find a copy of the correct DDS source in some
other library than where it would normally be expected? (Or, at least,
you might find a source member that is "close" to the correct version,
perhaps with a source changed date time stamp that is "close" to the one
used to create the *FILE.)

Then, assuming you still have the existing display file object, and you
can still run the application and see what the screen looks like, it
should be fairly simple and straight-forward to re-create the source (or
modify another "version" of that source as found above.)

First, issue DSPFFD against the display file object to see the record
names and field names, which includes all of the indicators, etc.

Then, examining the RPG program(s) that use this display file, and you
should be able to re-create it.

It is not a trivial exercise, but for a "one-time" situation like this,
this may be your best alternative.

Hope this helps.

All the best,

I know you can retrieve CL source if the CL program allows it.

But can you do that for a Display File? I don't see any command for that.

The object of the display file is there, it shows me in the description
where it was compiled from, but alas, no source.
It was compiled back in 2007.

Thanks.
