In programming in general, scope refers to the location in which a variable, function, or other object is declared. When referring to scopes in ENIGMA, we usually divide these into five categories, listed below in the order they are checked:

• The script-local scope refers to variables declared explicitly in the current script or piece of code using the var keyword or a C++ type. This scope can be referred to via dot access using the local keyword.
• The local scope refers to variables that are local to the current instance, such as my_health or my_life. These also include built-in instance variables such as x, y, hspeed, vspeed, alarm, etc. This scope can be referred to via dot access using the self keyword.
• The global-local scope is a more precise term for the built-in instance variables (x, y, hspeed, vspeed, alarm, ...). This scope does not actually exist in the same sense as other scopes here; it is more of a classification. This scope can be referred to via dot access using the local keyword. This scope is also referred to using the local keyword.
• The global scope is a single scope which can be referenced by all objects. This scope has two categories.
  1. The implicit global scope contains variables like room, health, score, lives, mouse_x... These variables can be referred to implicitly, just by name. This scope also includes variables declared using globalvar, or the global keyword followed by a C++ type name.
  2. The explicit global scope contains variables you assign using dot access with the global keyword.
