The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

I needed to debug a pgm in a development library. The developer had
compiled in a development source file QRPGLESRC, then copied to
another source file used for the deployment, deleting the original
in QRPGLESRC. When I do STRDBG, a source member shows up with the
message <File QRPGLESRC not available> and <File source modified>. I
don't know what source member is being displayed on the screen, but
it doesn't seem to be usable for debugging.
DEBUG(*ALL) gives you all debug views so you have *SOURCE, *LIST and
*COPY available. *LIST view effectively embeds the compiler listing
inside the module object so it is not possible to have the debug view
out of sync with the module. The messages you see relate to the source
view. What I suspect is happening is that *SOURCE view is the first
view selected by the debugger. There is a function key (which one
escapes me at present) in debug that can select from the available
views so if you select *LIST view you should be able to debug quite
happily.
Note that *COPY is just a fancy *SOURCE view that includes the copy
members.
For in-house code *LIST is probably the best view. It means debugging
can be performed wherever the *PGM object is located. If you have the
source on the production system then *SOURCE or *COPY will work well
too.
For code being shipped (i.e., vendors) then *SOURCE or *COPY is
probably better if only to avoid mistakenly shipping the source in the
*LIST view if you forget to strip debug data out before distribution.
Of course, with the new releases you can now encrypt the debug listing
so it might be worth shipping with encrypted *LIST to allow remote
debug on a customer machine.
