Thanks for using the application!

====================================

Scheme is one of the two main dialects of the programming language Lisp. Unlike Common Lisp, the other main dialect, Scheme follows a minimalist design philosophy specifying a small standard core with powerful tools for language extension. Its compactness and elegance have made it popular with educators, language designers, programmers, implementors, and hobbyists. The language's diverse appeal is seen as a strong point, though the consequently wide divergence between implementations is seen as one of the language's weak points.

Scheme was developed at the MIT AI Lab by Guy L. Steele and Gerald Jay Sussman who introduced it to the academic world via a series of memos, now referred to as the Lambda Papers, over the period 1975–1980. The Scheme language is standardized in the official IEEE standard, and a de facto standard called the Revisedn Report on the Algorithmic Language Scheme (RnRS). The most widely implemented standard is R5RS (1998), and a new standard R6RS was ratified in 2007.

Scheme was the first dialect of Lisp to choose lexical scope and the first to require implementations to perform tail-call optimization. It was also one of the first programming languages to support first-class continuations.

Scheme started as an attempt to understand Carl Hewitt's Actor model, for which purpose Steele and Sussman wrote a "tiny Lisp interpreter" using Maclisp and then "added mechanisms for creating actors and sending messages." Scheme was originally called "Schemer", in the tradition of other Lisp-derived languages like Planner or Conniver. The current name resulted from the authors' use of the ITS operating system, which limited filenames to two components of at most six characters each. Currently, "Schemer" is commonly used to refer to a Scheme programmer.

Disappointing.

The example program can be compiled and executed one time, producing the expected output. If you hit "Run" again, you will be prompted to buy compilations. That's fine with me, the first "compile and run" was successful, so I paid for unlimited compilations. This is where it becomes a disappointment: no matter what I type in my program, the output is always: "Wrong __data_start/_end pair". If I run the "Hello World!", without changing anything, it works as expected. If I modify it, even by adding a single character to the string being displayed, the result is "Wrong __data_start/_end pair". If I run an empty program, there is no output but that's expected. If I add an opening parentheses and a closing parentheses, the result is "Wrong __data_start/_end pair".

Why would I pay

I get the subscription model. The app doesn’t seem to be advertised as free to me so that’s fair. But I’m. It going to pay without at least getting a few free compilations to test it. That’s absurd.

Works like a normal scheme interpreter

It runs great, but I am slightly disappointed that you can only compile it so many times a day. I would also love to see the update they say is coming soon! But all in all, works great!
