====================================
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.

Does not work - don’t buy

To developer - will you be fixing this app since it currently doesn’t work for paying users. I’ll change my review once a fix is posted. Simple hello program ran but everything else fails with mysterious error message.
Disappointing.
Rickwaldron
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".
Figured with the new up dates it would work..

It wouldn’t let me leave no stars so 1 it is but it’s really a -5 stars, I’m not sure what this developer is doing with their life but how can I get a refund, as a CS student and a developer I’m pretty sure they just hard coded their example code to run and any other legit scheme code returns wrong __data_start/_end pair I’m gonna be getting on the line with Apple developer support and see if this app can be taken down till it actually works as it’s being sold as. This app is called scheme based on pyramid scheme to take money that’s not earned, not because of the programming language! ?
Why would I pay
King999
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.
This is NOT a free app!
Rand's Destroyer
You can’t execute a single line of code unless you pay. You can’t even test it. Thanks for wasting my time.
Daily limit on allowed compilations
NeuroDAH
Reasonable for compiling small bits of Scheme code. Comes with adequate reference material for teaching oneself the basics, or for reviewing. But to limit the number of compilations per day is false advertising for an app that is not free. Hence 2 stars rather than 4.
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!
Great App!
Zelah Hutchinson
I am writing a compiler that targets many languages and this app is ideal for my purposes. Keep up the good work!
