```
public static interface Jasic.Expression
```
Base interface for an expression. An expression is like a statement except that it also returns a value when executed. Expressions do not appear at the top level in Jasic programs, but are used in many statements. For example, the value printed by a "print" statement is an expression. Unlike statements, expressions can nest.
