Select Function: Notice that this selection will configure the
proper input and output pins for the function you select.
Editing UserFunctions: If you import a library of UserFunctions
programmatically, you will not be able to edit them. You can
view them and set breakpoints to debug. If you want to edit the
UserFunctions you import, use the Merge Library command.
Set Variable Caution: Notice that when you use a global
variable in a function, you have to remember to create that
global when using the function in other programs. One of the
advantages of explicitly creating inputs and outputs is that they
are easier to track.
