Quick question... how would one go about storing a set of variables in a subvariable... probably the wrong terminology for it.
so for example...
I want to store an
X coord
Y coord
Width
Height
Under a set...
Like if i were to call
button1.X
and have it return the X value
Hello,
Use a struct, or a class 
http://www.cplusplus.com/doc/tutorial/structures

2 ways.
A "struct". This is the older C way, but often still appropriate.
A "class". This is the newer C++ way. The door to the world of object orientation.
variables in a subvariable... probably the wrong terminology
In a struct, they are normally referred to as "fields". In a class, they are called "attributes".
The difference between 'struct' and 'class' is that until otherwise stated, members are 'public:' in struct and 'private:' in class. If you use a class, put the line "public:" at the top so code outside the class declaration can use the data.
class rectangle {
public:
rectangle(int inX,int inY,int inWm int inH);
~rectangle(void);
int X coord;
int Y coord;
int Width;
int Height;
};
And you just opened up Pandora's box..

THANK YOU!
Ive been playing with arduino and x for a long time now... but have never needed a structure... it helps to know the proper term lol

Yes! Knowledge links!!
I... probably should have thought of looking in the programming base instead of exclusively on arduino lol...
THANK YOU!!

But not until you fix the missing comma
Well, m is close to a comma.
