In start.a51, there is defined a idata segment ?STACK.
?STACK SEGMENT IDATA
Now, in my asm file, I want to use the ?STACK to reset the SP,when using it directly as follows,
mov SP, #STACK-1
but there is an error: "error A45: UNDEFINED SYMBOL"
How can I do it, thanks.
When adding "public Stack" in start.a51, all is ok. Thanks very much.
