async and await build on top of promises and generators to express asynchronous actions inline. This makes asynchronous or callback code much easier to maintain.

Functions with the async keyword return a Promise, and can be called with that syntax.

Inside an async function the await keyword can be applied to any Promise, and will cause all of the function body after the await to be executed after the promise resolves.

Intrinsic Functions are included in the COBOL standard as a set of functions that return values from a specific algorithm, given zero or more arguments. These intrinsic functions are provided as a facility of the compiler and runtime system. The return items are temporary COBOL fields, and can be character data, bit fields, or numeric values.

Examples include trigonometric functions, date time routines, data type conversions, standard deviation, and other support algorithms.
