OPENDIR number of files problem

[John Esak]

Yes, this is really strange.  Ken and I worked this out on my system last
week.  You can get around the opendir truncation to 3 digits by just using
@dirlist_rfilename["0"] (or any of the @dirlist variants) as the correct
number of opened files.

The *fact* that something can lie dormant like this for a decade... then
hits me... and within the same couple days a week it hits someones else.
Absolutely amazing.  Who had this problem after I found it a couple weeks
ago?  Was it you Bruce?

I mentioned this behavior to no one outside of my IT group. I always say
this reminds me of Star Trek's "hodgekiss Paralle Planet Development"
theory... or some such.  It was mentioned in the stupidest episode ever ...
the one about the Yangs and the Comes.... :-)  The Yankees and the
Communists.  It's amazing what actually gets into production... when I, at
least, have written a half dozen infinitely better scripts... not too
mention the hundreds and thousands of other published and non-published
authors in the world.  Just strange... and disheartening...

I'm curious, if this was you, Bruce... did it actually just happen to you
also???  When I worked with Ken on it, just recently... and we (he) found
the error... (but I pointed to the idea of what was happening by talking
about some limit in opendir(), so I feel pretty good about sleuthing it out
far enough for Ken to see it quickly... and presenting him with a table that
would produce the error immediately.)  Meanwhile, my situation also had over
2,000 files.  2780 roughly.  It just all sounds so similar to what happened
to you... and in the same week... really one of those hard-to-believe
things.  Maybe Lee Machan told someone about it... I had emailed him
regarding it... but he is in the IT group I work in now.  I know the others
don't have too much contact with the filePro community.

It's all just pretty strange.
