}}</ref> It was a typeless language, with the only data type being the underlying machine's natural [[memory word]] format, whatever that might be. Depending on the context, the word was treated either as an [[integer]] or a [[memory address]].
As machines with [[ASCII]] processing became common, notably the [[DEC PDP-11]] that arrived at Bell Labs, support for character data stuffed in memory words became important. The typeless nature of the language was seen as a disadvantage, which led Thompson and Ritchie to develop an expanded version of the language supporting new internal and user-defined types, which became the ubiquitous [[C programming language]].
