Unlike virtually every computer system in the world which uses a variant of ASCII, IBM mainframes and midrange systems such as the AS/400 tend to use a wholly incompatible character set primarily designed for ease of use on punched cards.

There are a few Keurig K-cups that DO contain calories. They fall under two categories. Brew Over Ice teas and coffees (except Twinings) and Cafe Escapes. Keurig has kept those around 60 calories each. When in doubt consider the consistency of the coffee. If it is creamy- it contains calories and most likely sugar. If it is a simple black coffee, calories are not an issue.
Strength of K-cup coffee. I was shopping for a new coffeemaker, and wanted one of the Keurig models. These use pre-measured k-cups of coffee, which you put into the machine, and in less than 60 seconds, your coffee is ready-to-drink.o fill a larger mug, I make multiple servings of the smallest size cup. I use 2 K-cups to make two 5+ oz. servings to fill a large travel mug (leaving some room for milk).
