zero page ram page memory mapping on STM8S003

on STM8S003F3U according to datasheet there is 1024(total ram) - 513(stack) = 510 bytes for user application: 256 byte in the zero page and (510-256)= 254 in Ram section.
If use the short stack compilation option all data are automaticaly maped in the zero page space and i have an error if i use more than 256 bytes.
if i use the long stack compilation data are mapped automaticaly in the upper page: the Ram page and i have an error if use more than 254 (normal because there is the end stack overlap)
I did'nt find any cosmic compiler user guide for stm8. If i try to use pragma to force linker to set data in different space the error is : pragma misplaced ...
How is it possible to use mixed data  mapping zero page and ram page ???
thank's a lot
