This is probably a very noddy question but I haven't resolved it after quite
a bit of source code hunting. I want to pass a string pointer as an argument
to an assembler function. Calls to other routines passing integers are
running fine. I guess I don't know how to declare or call it correctly, but
can someone point out my mistake?

extern void Passt(char *whatever);
char *S;

...<snip>...

S="AABB"
Passt(S);

Gives linking error as follows in the line above:

    Error: undefined reference to `Passt(char *)'

TIA.
