BSL does not support weak typing. You need to specify your types when making declarations, as seen in the above examples. You can choose from "bool", "int", "float" (rarely useful because of BSL's limited math operations), and "string". As with C, you use "void" to mean "no type" when defining functions. | BSL does not support weak typing. You need to specify your types when making declarations, as seen in the above examples.
