Declaring variables

short      -32,768 to 32,767 
long      -2,147,483,648 to 2,147,483,647 
float      1.18E-38 to 3.40E38 (precision = 7 digits) 

You can declare three types of variables through scripts and as global variables. Variable names are not case sensitive. Declare with type and name:

short myShortVariable 
long  myLongVariable   
float myFloatVariable 

Scripts can also declare and use reference variables:

ref      myRefVariable
