Startup code

Seems likes I've found the way. In your startup.a66 find the following:

?C_RESET        PROC TASK C_STARTUP INTNO RESET = 0
?C_STARTUP:     LABEL   Model

...

?C_RESET        ENDP
?C_STARTUP_CODE ENDS

C_RESET        PROC TASK C_STARTUP INTNO RESET = 0
PUBLIC C_RESET
?C_STARTUP:     LABEL   Model

...

C_RESET        ENDP
?C_STARTUP_CODE ENDS

extern void C_RESET(void);

Cool! Thanks Mike, I'll give that a try

I must say, I've never understood the use of ? instead _ in the assy. files. Since ? is an illegal C start char for a label means we can never extern these labels. Most implementations use a leading underscore. I see your fix should work but does it have any other implications?

It did it again :-((
- second try -
I thought that was the whole idea of using '?': the user should not have access to such sort of things, although it's nice to have it sometimes. A bit more flexibility would not hurt since we are already allowed to edit startup.a66.
As for unexpected implications, I don't think there are any. ?C_RESET is a local symbol, so no side effects outside startup.a66. None inside also, at least it seems so.

Oh. Okay, then maybe the correct method should be to define a global label in the file for use by C functions that is set equal to the ?C_RESET label?

That was my initial idea, but I didn't want to work through the assembler manual to find out how it's done. Defining an independent global label seen by C mudules would be a safer way.
