To determine which Synergy data types can be used as return values, see the Where data types can be used table. For strong prototyping, it is best to specify the return type of all functions. Methods require a return value; VOID is a special return type that you can use to indicate that a method does not return a value.
In traditional Synergy, a return value cannot be a pseudo or real array; for methods, return values may be dynamic arrays of objects. ^VAL indicates that the return type is a native int passed by value. On 32‑bit platforms, return types on functions cannot be bigger than i4.
