NOT DECLARING

if (rc_dig_in01 == 0)

pwm01 = 0;
}

(pwm01 would stay at the value 0 when button is pressed. Once its unpressed, the value will stay at 0.)

Unless something else assigns a different value to pwm01, that is correct.

You seem to be under the impression that "declaring" a variable works some magic that keeps setting it to a specific value. If you want pwm01 to always be 127 when the button is released, you'll have to do it yourself. Either

pwm01 = 127;
if (rc_dig_in01 == 0)
{
    pwm01 = 0;
}

or

if (rc_dig_in01 == 0)
{
    pwm01 = 0;
}
else
{
    pwm01 = 127;
}
