XDEF Entry and ABSENTRY Entry error

ashchand — Sat, 20 Jun 2015 02:07:17 GMT

Hello everyone,

This is the second program I have written in assembly language and I am getting "error A1104: User undefined symbol: 'Entry'". Which is kind of weird because it worked fine in my first program. I am running code warrior for hc12 on parallels on my macbook pro and here is my code:

; export symbols

XDEF Entry, _Startup ; export 'Entry' symbol

ABSENTRY Entry ; for absolute assembly: mark this as application entry point

; Include derivative-specific definitions

INCLUDE 'derivative.inc'

DATAStart EQU $0800 ; absolute address to place variables

DATAEnd EQU $0BFF ; last address of RAM, used to init stack pointer

ProgStart EQU $0A00 ; absolute address to place code/constant data

; variable/data section

ORG DATAStart ;starts storing data at location 0800

NUM DC.B 9

DEN DC.B 5

RNDVAL DS.B 2

;Calling Program

ANDCC #$7F

LDS ProgStart ; loads stack pointer to 0A00

LDAA NUM ; loads NUM to register A

PSHA ; places NUM in stack frame

LDAA DEN ; loads DEN in register A

PSHA ; places DEN in stack frame

DES ; creates space for return value

JSR ROUND ; jumps to sub program ROUND

PULA ; retrieves result

STAA RNDVAL ; stores result in RNDVAL

INS ; recovers dynamic memory used by DEN

INS ; recovers dynamic memory used by NUM

STOP ; terminates program

;Sub Program

ORG $0B00 ;absolute address to store sub program

;prolog code

ROUND PSHA

PSHB

PSHX

PSHY

;Algorithm

TSY ; loads pointer to y

LDAA #0 ; loads zero in register A

LDAB 11,Y ; loads NUM into register B

LDX 10,Y ; loads DEN into register X

IDIV ; divides A+B by X

LDAA #2 ; loads 2 to register A

MUL ; multiplies 2 x remainder

XGDX ; switches 2*R to X and Qout to AB

CPX 10,Y ; compares double remainder to DEN

BLT SKIP ; if x is less then den

RTS ; returns back with HI (7,Y) and LO (8,Y)

SKIP ADDB #1 ; else round up one

STAB 9,Y ; stores B in return value

;epilog code

PULY ; stores Y HI 1,Y and LO 2,Y

PULX ; stores X HI 3,Y and LO 4,Y

PULB ; stores B in 5,Y

PULA ; stores A in 6,Y

RTS ; returns back with HI (7,Y) and LO (8,Y)

;**************************************************************

;* Interrupt Vectors *

ORG $FFFE

DC.W Entry ; Reset Vector

As you can see my code was complete and I was just debugging each line to see if it worked, but i got stuck in the first line. Any help would be appreciated.
