Re: Qualified Data Area array

[Scott Klement <klemscot@xxxxxxxxxxxx>]

FYI, I looked at your reply (quoted below) in 3 different e-mail clients,
all of which are HTML capable, but all of them display lots of HTML
codes which make the message hard to read.  Something is up, either with
your client or the list.

But, since your message is short, I'll decode the HTML manually... so
here's my reply...

Yes, the "S" in column 24 tells you that they're "standalone".

The DSPLY op-code is limited to 52 characters.  So, I made testpath 52
so that I could use it with DSPLY.  If I were using it for some other
purpose, I would've made it longer -- but this was just a demonstration.

Actually, I usually use at least 256 for pathnames!

Correct.  That's what makes pdfloc overlay ds1.   Notice the line that
says p_pdfloc = %addr(ds1)?  The idea is you get the "address" (i.e.
location in RAM) where ds1 is stored, and you make pdfloc use that same
space in RAM.   That way, populating one automatically populates the
other.

Here's the way your message looked in my 3 different mail clients:
