Variable type

A simple S variable can be one of the following three types:

• STRING with the value range <c-string 0..4096>

• INTEGER with the value range <integer -2147483648..2147483647>

• BOOLEAN with the value TRUE or FALSE

These three types are subject to a rigid set of type rules: a variable type can only be converted to a different type by means of builtin functions (see the “SDF-P” manual [34]).

In addition, there is also the variable type ANY. In this case, the variable is given the same type as the value assigned to it. The current type can be changed at any time by means of an assignment.
