i can choose channel like that:

setup_port_a( ALL_ANALOG );
setup_adc( ADC_CLOCK_INTERNAL );
set_adc_channel( 0 );

but i can get data with;
value = Read_ADC();//

can i get data 10bit via this way or any thing i mus do?

See the CCS example file, EX_DOT.c. It shows how to read two A/D
channels sequentially:
c:\program files\picc\examples\ex_dpot.c
