How would you declare a pointer to a far array that's in local memory?
No matter what I do the compiler pukes (DC v10.64).
const far char myarray[] = "my message";
...
far char *p;
p = myarray; <--- WARNING: Incompatible types!

Have not tried it in DC (just Softools) but would be
char far * p;
May need to be:
const char far * p: since it is pointing to a const array. Can always be
cast as needed.
'far' operates to the right so it says the '*' is far.
far char *p;
says that p will be stored far but still is a pointer to near.

It was the "const" the compiler was complaining about.
Once I added a cast the warning goes away.
FYI, according to the DC manual, "far" can go on either side of the
base type. So "far char *" is just as good as "char far *".
Thanks.
