Tolong jelaskan mengenai Execution semantics dari Basa program dalam bahasa sunda

Once data has been specified, the machine must be instructed to perform operations on the data.  The execution semantics of a language defines how and when the various constructs of a language should produce a program behavior.

For example, the semantics may define the strategy by which expressions are evaluated to values, or the manner in which control structures conditionally execute statements.
