FLOW is an educational programming language designed by Jef Raskin and Jonathan (Jon) Collins, an undergraduate student in the UCSD Art Department, in 1970 and implemented on several minicomputers in the early 1970s. The goal of the language is to make it easy to explore algorithms through a highly interactive environment. The overall language is very similar in syntax and structure to the BASIC programming language, but has a number of changes in order to make typing code easier. Most notable among these was the concept of "typing amplification", in which short strings, often a single character, were expanded by the language into the complete "unamplified" source code. Modern integrated development environments and code-oriented text editors often include a similar feature, now normally r
