I'm looking for a resource to anything having to do with using the
(Apple ][) ROM to get a line of applesoft code and display it on the
screen.
I understand from searching the Net (What's Where in the Apple) that
there was an article from Apple Orchard Vol 1 Number 1, pg 13 that
explained the AppleSoft LINGET routine. Is there an on-line resource
for that magazine? I've looked to no avail.
Was there an effort or book that tore apart the ROM routines, and
really looked in-depth as to what they did? What's Where in the Apple
always seemed too light on explanations.
A pointer in the right direction would *really* be appreciated. I've
been away from this sort of thing for decades. Using AppleWin
emulator.
Thanks in advance,
GoldenHound
I don't know about the Apple Orchard article but you can find the
commented source for Applesoft here:

Hi Charlie,
Thanks for the reply to my post. I actually did find this in my
search, so its nice to know others think the same way.

This is a fine disassembly, but it would be much more useful to
have the entire assembly in one, searchable file--a .pdf, for example.
Having to separately search many files is a nuisance.
Another great disassmbly is Glen Bredon's Sourceror, which was on
the flip side of the 5.25" Merlin 8 distribution disk. It assembles
a complete, commented Applesoft listing which can be easily searched.

Yes - I do recall that listing. I had Merlin back in the old days,
but
I don't believe I ever paid as much attention to that Sourceror
listing.
That's a good idea. I'll have to take a look at it.
My hope was to find a good article on the why's and wherefore's things
happen - to hold my hand, so to speak, regarding those internals.
Thanks for the pointer!
Regards and a belated Happy Easter,

I took my issue of Golden Orchard and will scan the pages for you
tomorrow,

The closest I'v seen to what you describe is the Call-A.P.P.L.E.
"All About Applesoft" volume, and though it has useful descriptions
of the functions of many Applesoft entry points, it is not a thorough
dissection of the ROM.
It focuses more on entry points that are likely to be used in a M/L
extension to Applesoft than on the "housekeeping" routines.
It is a good complement to a ROM disassembly, however.
$D6A5 is the start of the LIST routine in the ROM. That would
be a good place to start looking.
FAN...TASTIC! Thanks very much Antoine. A very nice scan indeed -
You did a great job.
I couldn't have asked for better!
Well, my birthday isn't for a month yet, but I can't think of a better
present.
Happy Birthday to me...Happy Birthday to me...
Fine Regards, and again Thank You for going to the trouble of sharing
that information!

If you were in an Applesoft program, LIST <nnnn> would do it. ;-)

LINGET collects an ASCII line number and converts it to binary.
The file name begins with "theappleorchard"
There is a bitmap PDF and a OCRed PDF.
