CANT RUN THIS !!! error in export symbols ????? can any one check it

; Include derivative-specific definitions

INCLUDE 'derivative.inc'

; export symbols

XDEF Entry, _Startup, main

; we use export 'Entry' as symbol. This allows us to

; reference 'Entry' either in the linker .prm file

; or from C/C++ later on

XREF __SEG_END_SSTACK ; symbol defined by the linker for the end of the stack

; variable/data section

MY_EXTENDED_RAM: SECTION

; Insert here your data definition.

Counter ds.w 1

FiboRes ds.w 1

; code section

TAA EQU $800

TBB EQU $801

LDAA #100

STAA TAA

Hello

There are a couple of issues in the snippet you have provided.

In there you have a comment

; code section

This is not enough to define a code section for your application. You need to define a code section as follows:

MY_CODE: SECTION

Next you need to define a label for the beginning of the actual code.

For instance:

main:
LDAA #100
STAA TAA

Finally you have no labels Entry or _Startup in your code. So you need to remove those symbol names from the XDEF line

Once that is done you should be able to assemble the source file.
