Now for what is no doubt a very stupid question that I'm hoping
someone can help with.
I'm using "Turbo Macro Assembler '05", and have verified that it
works with the following simple little program that I got off the web:
* = $1000
loop: inc $d020 ; increment $d020
jmp loop ; jump to label loop
I can get <-- 3 "Assemble and run" to work just fine, however while
<-- 5 "Assemble to disk" seems to work, how on earth do I execute the
program that is created? Obviously I need to do a:
LOAD"FLASH",8,1
It loads just fine, and I assume I need a SYS statement with an
address to start it, but what on earth should that address be?

I don't know if TMA needs you to specify a starting address to assemble
to disk; most of the hosted assemblers don't, but many of the cross
assemblers do (xa does, for example -- I need to make a FAQ about that).
Assuming it does not, SYS 4096 will run it.
Assuming it does (the computer crashes), add a .byt $00, $10 above the *=
(some assemblers will accept .word).

I'm guessing the computer crashes when I try to run it with a SYS
4096, it puts me back at a "READY." prompt. Adding ".byte $00, $10"
at the beginning of the source prevents it from even compiling.
I've gone ahead and posted a question about this to comp.sys.cbm as well.
On a positive note, I *FINALLY* found my Wico Command Control
joysticks, and the Atari 2600 sticks! Based on the box they were in,
I don't understand how I missed finding them a couple weeks ago when
I pulled the C64 out. Also found the Power Supply for the A500, and
the 2002 monitor cable, so I'm about to see if the A500 still works
:^) Now where did I put the copy of Overlord/Supremacy for the A500
:^)

I converted the HEX addresses that the assembler gave me when I
assembled to disk, and managed to figure out that I needed a "SYS
1000".

Did you forget the $?

Now we all expect an uber-cool graphics demo from you soon with

OK, any recommendations on tutorials for learning Assembly Language on the
C-64? The books I have seem to be generic 6502 books that predate the C-64.
BTW, don't expect to see any uber-cool Demo's from me anytime soon. I've
been playing with the C-64 when I should really be working on a couple other
projects. :^)

When you say learning assembly on the 64, was there something in particular
you wanted to learn how to do?
COMPUTE's Machine Language for Beginners is a good book, but it's mostly
6502 in general with some Commodore-specific sections. But I learned the most
about Commodore programming from Mapping the 64 and the PRG.

Another good one is "Machine Language for the Commodore 64" by
Jim Butterfield.. There is text version here:
http://www.geocities.com/ResearchTriangle/Lab/1767/files/c64/ and
select "ml4c64.zip". His writing style is a lot like how he gives
presentations. :)

I remember the first time I tried assembling some simple little program to run
under CP/M, and making exactly that mistake -- "ORG 100" instead of "ORG
100H" or whatever the syntax was. It crashed and burned, of course, and
provided some rather interesting (for a minute or so) graphic patterns on the
screen before I hit the reset button. :-)
