| 26 | wikipedia.summary | 1618 | 34% | Blitz BASIC refers to the programming language dialect that was interpreted by the first Blitz compilers, devised by New Zealand-based developer Mark Sibly. Being derived from BASIC, Blitz syntax was designed to be easy to pick up for beginners first learning to program. The languages are game-programming oriented but are often found general-purpose enough to be used for most types of application. The Blitz language evolved as new products were released, with recent incarnations offering support for more advanced programming techniques such as object-orientation and multi-threading. This led to the languages losing their BASIC moniker in later years. | What is the text summary of the language from the Wikipedia page? | wikipedia.grammar | |
