I'm afraid that's not what I meant (I guess my paragraph was ambiguous).
What I need is a "common" definition that is in the MIDDLE of the data, so
the program can use a signed char to access it (pretty wierd huh!).  I
can't get this to happen in the BSS subspace.

BTW: the 800 assembler requires a label for the .COMM directive.

On a related issue (yes still KCl), is there any way to use the value of
$global$ in a C routine? (The C compiler doesn't like the $).  I could get
an assembler routine to put the value in a global, but that means a memory
dereference every time a certain macro is used (rather than constant
folding done at compile/link time).  I'll probably just hard code 0x40000000.
