Can you help me to figure out how to use MIT Scheme? The Edwin editor. There is a huge field to type but it doesn't respond. It allows me to evaluate expressions in the bottom tiny field only when I type esc twice in a row.

Have you tried to read the manual or to use the online help? – Rainer Joswig Jan 10 '18 at 23:49

@RainerJoswig Yes I did. Several times. It didn't help. – user13 Jan 11 '18 at 00:07

Are you able to do a `Ctrl-x Ctrl-e` to evaluate the `564` shown in your picture? Reference: https://www.gnu.org/software/mit-scheme/documentation/mit-scheme-user/Edwin-Scheme-Evaluation.html – Flux Jan 11 '18 at 20:23

@Flux That is the problem. I read it. It doesn't do anything. It just types C(Ctrl)-x in the bottom part instead of 'Evaluate expression:' that is shown in the picture. – user13 Jan 11 '18 at 21:38

Wondering if this problem is related to windows possibly eating certain control sequences? Your description sounds like the C-x is going through, but maybe not the C-e? – John Clements Jan 11 '18 at 23:50

@JohnClements C-e just brings the pointer from the right to the left and do nothing. – user13 Jan 12 '18 at 00:04

1The only thing that works is M-z – user13 Jan 12 '18 at 00:05

Wait... from the right to the left, or from the left to the right? – John Clements Jan 12 '18 at 18:11

I'm sorry. From the left to the right. – user13 Jan 13 '18 at 12:46

I think you should keep the Ctrl key pressed, when hitting `x` and then `e`. do not release the Ctrl in between. are you doing it this way? – Will Ness Jan 14 '18 at 19:00
-
@WillNess Yes, sure. I am doing it that way. – user13 Jan 14 '18 at 22:50

on Win7 [it works](https://imgur.com/a/fzKEd). both tutorial and info do not though. something's broken. – Will Ness Jan 16 '18 at 10:48

if M-z is working then you don't really have a problem, only the inconvenience of having to put naked values into a form, like e.g. `(car (list 564))`. – Will Ness Jan 16 '18 at 11:10

Thank you to everybody. Since figuring out that M-z works I have been using M-z and mostly it satisfy my needs. Thanks! – user13 Jan 16 '18 at 18:03

you can post your own answer and accept it, to signal that the issue is resolved. – Will Ness Jan 19 '18 at 20:32

Edwin is an editor; it is not a interactive shell. The big empty space is used to write a scheme file. I think you to work in an interactive shell.
Open a console window and type "scheme" to work in an interactive shell. To write a scheme-program-file you can use an editor in ascii-mode. Use the suffix "scm" to store the file. To run it, type in the scheme-shell:
(load "start.scm")
40 years ago scheme and edwin were distributed by texas instruments. With these tools I started to love programming. Today I am working under ubuntu and I am using emacs as editor and a bash-shell running MIT/Gnu-Scheme. 5 year ago tryed edwin agin, but I preferd emacs.
The most people would suggest to use DrRacket. What Operation System you are using?

Do you write it for ubuntu? Because in windows typing "scheme" brings a response that it is not an internal or external command... – user13 Jan 14 '18 at 22:54

this answer is wrong. I installed MIT Scheme; typed the code form by form into the same "big empty space" as shown in the question, pressing C-x-e after each, and [it worked](https://imgur.com/a/fzKEd) as an "interactive shell". The only difference is, I installed it on Win-7 box. – Will Ness Jan 16 '18 at 10:47
