I'm trying to learn how to make my first useful externals from scratch. I managed to use a float argument, as in the famous counter example, passing a float argument. But now I'd like to be able to take a symbolic argument, a string of characters (something that I'll use within a sprintf to get a correct formatted string later). A name, basically
It's stupid, but couldn't remember a simple external using only a symbol as argument to get inspired from. Could someone point me to a simple external source that could serve as an example ? I know i will have to put A_DEFSYMBOL in the setup routine, but besides that I'm not finding my way out.
I'll be away from keyboard for 20 days so no matter if you take your time
