There is one builtin "variable" and a number of builtin variable arrays available in SLIC. This document contains a complete reference of the data that can be extracted from these types. Note that for types supported as user types, all the members of these variables can be accessed in user variables as well. For example, the builtin unit array has a member named owner, which means that any variable of type unit_t also has a member named owner. Member data is accessed using standard c style dot notation. The one plain builtin variable is named "g" and contains three members:

• g.year - the current round
• g.year_str - the current year in string form. Only useful in string replacements.
• g.player - the current player The rest of the builtins come in arrays, which are filled in when an event handler is called (but can also have values assigned by script code).

• unit.location - the unit's location
