Port A on PIC16F876

hi,
Could some one tell me what is the best way to configure PORT A as digitalouts on the PIC16f876. The datasheet says that the ports are configured as analog inputs by default. Presently I am using the following to configure PORTA as digitals. I am not sure if I need to add something more.

#use fast_io(A)

main(){

set_tris_A(0x00);
SETUP_ADC(ADC_OFF);

while();
}

That's one way to do it. An easier way is to get rid of the #fast_io()
statement and use the CCS pin i/o functions, such as output_low,
output_high, input(), output_float(), output_a(), input_a(), etc.
In standard i/o mode, the compiler will automatically set the correct TRIS
for you. Standard i/o mode is the default mode of the compiler. You
don't have to specify it.
