Any way to send variables to afunction/procedure

I guess because they are trying to keep it fairly simple so that even
numbsculls like me can use them. On the positive side, look how easy they
have made serial communications and the fact that they supply voltage
regulation, data storage, serial port on any pin etc etc etc etc , the goods
easily outweigh the bads.
