Since _main is a global function defined in another file, I do notice
that it does link up the right address.  I checked the srec again and
can see it is correct.  It's just odd how it does not ever seem to get
there to the compiled 'C' portion when I burn a prom for the SH1.

I tried your example above but I get the error 'bad expression' when
using 'bra @r4'. The expression:

jmp @r4 

does compile ok, however.  I'll give it go again when I get to my prom
burner.  Thanks for your help.

Robert
