Massimo,

I am new to sdcc and Pic in general but I think the answer to your question is to specify the address location of your variable when you declare it and then point your assembly to that spot when you want to access it in asm. http://particle.teco.edu/software/sdcc/example.html
This page has a good reference on converting other compiler code over into sdcc code. In their example they declare some unsigned int with

uint8_t at 0x10 foo;
uint8_t at 0x11 bar;

My guess is you can access them in asm via the address you gave them in your code.

Hello,
       I'm using SDCC on PIC 16F target. Now I need to use inline assembly
function to manage data on local variables. How can I use local
variables within inline assembly code?
My case is:

unsigned char handle (unsigned char data) {
       unsigned char temp;
       _asm
               some_assembly_manipulation on temp
       _endasm;
       return temp;
}

I can't find the way to reference variable 'temp' in inline assembly code.

Thank you,
       Massimo.
