void	not currently supported

These are the currently supported data types in messiah:script. As described in Variables, these names are used to specify the type of a variable when it is declared, or to specify the type of return value from a function or the types of the arguments that it accepts.

All of the above types are static (that is the types are static or "don't change", not to be confused with static storage described in Variables) except for 'dyna'. The 'dyna' type can change it's underlying type based on the value that gets assigned to it:

dyna a = 3.14; // a is a double
a = "test"; // now it's a string
a = CurObj(); // now it's an object

Wow, 'dyna's really cool! Why would you need any of the other types? Because they're a lot more efficient. Since 'dyna' can't make any assumptions about the type it refers to it can't user a lot of the optimizations that the other types can. In general you should avoid 'dyna', use it only when it will really be convenient.
