Hi group,

Currently I work through the book of G Springer about Scheme using TeXmacs/Guile.

Until ch. 5 there were no problems and all programs run like a charm.

Now in Ch.6 about input/output I run into problems.

Here is a typical one.

;------------------------------------------------------------------

; - Program 6.6, pg. 174 -

(define read-demo

  (lambda ()

    (display "Enter data (enter done when finished): ")

    (let ((response (read)))

      (cond

        ((eq? response 'done) (display "Thank you. Good-bye."))

        (else (display "You entered: ")

              (write response)

              (newline)

              (read-demo))))))

; - End Program -

;------------------------------------------------------------------

Is it possible to use Texmacs-Guile interactive?

I know: use ‚format ..' instead of write/display ..

But what to do with (read) ??

How to work with user input and output?

Any hints or making the program about working are very welcome-

Best, Wolfgang
