Question on HVars

[leprechaun]

As a last attempt I try to be more precise with my questions.

Ok here is the problem:

In home I can define, say dd:=1. I am then asked if I would like to create user variable dd. If I accept dd shows up in var/user. Interesstingly the menu is program variables. HVars returns dd in a List.
Everything fine. (Maybe the fact that my numeric var is called a program variable is surprising)


Now still in home I define ee(X):=X. That is syntax error! Same with ee(x):=x.

In cas I can define a function. I can access it from home but it does not show up in HVars.

Question: what is it about user defined function in Home?
How do I define a user function in home at all?
What is the (obvious) difference on where I define a User function.


I hope someone might ne able to help.
