LOCATE s_uninit_data at $800

LOCATE s_nvrblock at $900

DEFINE __low_data = BASE OF s_uninit_data
Using
LOCATE s_uninit_data at $800
or
LOCATE s_uninit_data at LOWADDR OF EDATA
gives the same address (the lowest possible address) when RANGE EDATA $800:$BFF .
If
LOCATE s_uninit_data at $800
is changed to
LOCATE s_uninit_data at BASE OF EDATA
the lowest used address is $900 (because LOCATE s_nvrblock at $900 and
s_nvrblock is in EDATA ).

address space. The value of COPY BASE is treated as an expression value.

COPY TOP
