/* RAM allocation */
LOCATE s_uninit_data at $8000
LOCATE s_nvrblock at $9000
DEFINE __low_data = BASE OF s_uninit_data
Using
LOCATE s_uninit_data at $8000
or
LOCATE s_uninit_data at LOWADDR OF RAM
gives the same address (the lowest possible address) when RANGE RAM $8000:$BFFF.
If
LOCATE s_uninit_data at $8000
is changed to
LOCATE s_uninit_data at BASE OF RAM
the lowest used address is $9000 (because LOCATE s_nvrblock at $9000 and
s_nvrblock is in RAM).
