Re: QFileSvr.400 usage -- MIDRANGE-L

Peter:

Nice discussion and I agree with your clarifications. And to tellthe truth, I hadn't even looked at the REPLACE(*YES/*NO) before.When I first needed to code a CPY command, ISTR, either the parmdidn't exist yet or there were problems with it that made itunreliable. Perhaps I never went back to see how CPY had improvedover the years.


A couple more comments...

What I would expect to work is

 CPY OBJ('/QSYS.LIB/ROBDELME.LIB/DELETEME.FILE')
         TODIR('/QFileSvr.400/GDIHQ/QSYS.LIB/ROBDELME.LIB')

But [DELETEME.FILE] is treated as a subdirectory as far as itsmembers are concerned. Therefore, [DELETEME.FILE/*] _might_ be moreappropriate? The <help> for the parm gives some interesting hintsabout what happens when OBJ() is a directory.

Which brings up the subject my buddy & I have agreed to disagree on --is QSYS.LIB in the IFS or is the IFS in QSYS.LIB?

I _think_ that that is similar to asking whether Desktop containsMyComputer on a Win2K system, or MyComputer contains Desktop.

AFAIK, the concepts at work behind Desktop<->MyComputer are also atwork behind QSYS.LIB<->IFS in high-level principle. IIRC, back whenthe IFS started out, it was kind of "inside" QSYS but the various UIelements forced us to perceive it otherwise. As long as programmerscannot access below TIMI directly, we can only see what we're shown.

That is, if you materialized the QSYS 'context' and startedfollowing various pointers and offsets and whatnot, you could end upat some kind of object that would represent "the IFS". It wouldn'tbe any kind of object that was available to HLLs (nor perhaps evento MI?), but it would have a type/subtype and essentially "contain""pointers" to the various file system "objects", one of which wouldsomewhat point back to the QSYS "object/context".

(None of that is intended to be a valid technical description. It'smostly just verbalization of how I made sense of things for myself.)

Now, my recall might be faulty, my info might've been wrong, and myreference to QSYS.LIB might need to be something more like "themachine context" or some other esoteric term. Further, even if itwas like that back then, it could be totally different today. Butfor me, by looking at how Desktop<->MyComputer relate, I can atleast make a little conceptual sense of QSYS.LIB<->IFS.

Whether the mental imagery works for anyone else...? When a pointerleads to a pointer that leads to a pointer that refers back to thefirst, which one is the outermost?
