Functions take up too much DATA space

Hi,
I have a few functions in my 8051 firmware that have a few byte parameters in them, and I noticed that these parameters are stored in DATA space, making me run out of DATA space since I only have 128bytes to work with.

Is there any way of storing these parameters in xdata instead? I noticed that I'm only able to store byte pointers to xdata by using the "xdata" qualifier. The qualifier doesn't work on regular byte parameters.

OK, I tried declaring the functions as large and now they don't use DATA but rather xdata, with a slight increase in code space. Other than this are there any other implications?

The project is built using the small memory model if that makes a difference.

use linker script to link your data and code space according to your needs.. that might help you..

do you have xram on board?
