variablein
Variablein is a term used in programming and data modeling to denote an input variable within a computation or dataflow. It is not an official keyword in mainstream languages, but appears in discussions, tutorials, and some domain-specific languages as a way to distinguish input variables from internal state or outputs.
Origin and use: The construction blends "variable" with the preposition "in," echoing how some languages designate
Examples: In a hypothetical DSL, a function might declare its inputs as "variablein a" and "variablein b,"
Alternatives: Operators and conventions such as parameters, arguments, input ports, and in/out annotations serve similar roles.
