"The Three Faces of SiMPLE"

SiMPLE is a programming language that comes in two slightly different "flavors" -- "Pro-SiMPLE" (an older version which runs in the DOS environment), and "Ultra-SiMPLE" (a newer version which runs in the Windows environment). Because they each run in a different environment, Pro-SiMPLE and Ultra-SiMPLE can be thought of as existing in two completely separate "universes".

(In fact, portions of them are actually located in physically separate folders on your hard drive.)

However, even though Pro-SiMPLE and Ultra-SiMPLE may be physically separate entities, they both have many functionalities in common.

(For example, both Pro-SiMPLE and Ultra-SiMPLE use exactly the same keywords, they both let you perform arithmetic calculations, they both let you draw lines and circles, etc.)

"Micro-SiMPLE" (our training language) is merely a subset of the overlap area:

When we use the generic term "SiMPLE" (without a specific prefix of "Micro-", "Pro-", or "Ultra-"), we are usually referring to the entire colored area in the above Venn diagram.
