Systems programming language

System languages, in contrast, are designed not for compatibility, but for performance and ease of access to the underlying computer hardware while still providing high-level programming concepts like structured programming. Examples include Executive Systems Problem Oriented Language (ESPOL) and Systems Programming Language (SPL), both of which are ALGOL-like in syntax but tuned to their respective platforms. Others are cross-platform software, but designed to work close to the hardware, like BLISS, JOVIAL, and BCPL.
