He's obviously working in base 10, BDD, at least in the source. And 30004 #0 is his way of saying

.......NOPE... your wrong. When I started learning assembly.. I couldn't take the hex, so I built an assembler that
did everything entirely in decimal... and then has my ...

I am sorry about being a big pain in the butt about this (putting it mildly)...

I figured out what the bug was... take the basic

10 IF C<16 THEN C=C+1:GOTO 10
20 C=0:GOTO 10

Now take what I did...

10000 JSR A
10003 JSR B
10006 JSR (END..BACK TO COMPUTER PROMPT)

A IF C<16 THEN C=C+1:GOTO A
*(IF ...

Whoop... I this instance, I want to loop it back to the IF statement... creates an endless loop...

What is wrong with this logic... I am trying to build a 16 bit IF THEN statement... such as

IF C < 16 THEN (Pass thru to argument...
(If failed...RTS)

Assume these are the current values...
30005 #0
30004 #0

30016- AD 35 75 LDA 30005
30019- C9 00 CMP #0
30021- 90 0A BCC 30033
30023- D0 07 BNE ...

I had somebody from the Apple II forum help me with a specific routine that uses partial ROM routines to help... still not concise code but it works (*Only for APPLE II 6502)

Place your 3 binary values (24bit number) into Y,X,A from highest to lowest...

30032- AC 39 75 LDY 30009
30035- AE 38 75 ...

I forgot... cant use tables... its actually going into a Compiler... now I really sound off my rocker.. cant program ASM but making a compiler..... don't worry bout me... I had to make an assembler before I could program ASM at all... long story!

If I have 16 bit number... say (2) (2) that means its 2*256+2 or 512+2 or 514 final result. How do I output that 514 to the screen... (its apple ii, I know the output routines....) how do I get the two bytes to equal 5 1 4 so I can output them... or similar?!?

I need HELP... i am a serious idiot... The 6502 LINK above this one has two routines... I coded it exactly as above (2nd routine)... placing in one set of numbers at 25000 and the other at 20000 (25001, 25002 ect, 20000, 20001)... if I input in the two original positions 1 and 1 (signifying a number ...

This is reference material... question afterwards....



Here is an equivalent routine for converting 16-bit numbers: ; Convert an 16 bit binary value to BCD
;
; This function converts a 16 bit binary value into a 24 bit BCD. It
; works by transferring one bit a time from the source and adding it ...

If you have a multi-byte value... for instance... say b1= (2) b2= (2) that equals 514 in decimal... how would you code... loading those two bytes to print the decimal representation...?

I'm pretty much going to end the thread because the objective has been completed... but something opened my eyes about this assembly stuff just talking with you guys. I've had a couple of books in front of me and been reading them almost every weekend, and it might as well have been in greek or ...

This is an example of the LoRes Graphic Digitizer for Apple II your 'simple help' allowed me to do...

And also ended a year's worth of confusion reading assembly books, but remaining in the fog despite many weekends scratching my head! Thanks again! -Tom

Something clicked around 3am this morning.... I get it now, at least the basics. I even wrote a little code this morning after a short nap, and it worked flawless the first time with no debugging! I couldn't understand that there are 3 reg's, the X, the Y and the Accumulator. Even went back and ...
