gollark: > The language is unusual in having only one data type: a word, a fixed number of bits, usually chosen to align with the architecture's machine word and of adequate capacity to represent any valid storage address. For many machines of the time, this data type was a 16-bit word. This choice later proved to be a significant problem when BCPL was used on machines in which the smallest addressable item was not a word but a byte or on machines with larger word sizes such as 32-bit or 64-bit.[citation needed]
gollark: SOME people call it Basic Combined Programming Language.
gollark: Bee Control Programming Language is VERY cool!
gollark: (Bee Control Programming Language)
