# Inconsistent output in REPL
|
||
|
|
|
||
|
|
When doing the examples in the _Practical Common Lisp_ book I had confusing output in the repl when prompting the user for CDs using SBCL.
|
||
|
|
|
||
|
|
```
|
||
|
|
; Dedicated output stream setup (port 46185)
|
||
|
|
; Redirecting all output to this MREPL
|
||
|
|
; SLY 1.0.43 (#<MREPL mrepl-1-1>)

Apparently a similar issue was first found on MacOSX and later confirmed on Arch.
|
||
|
|
|
||
|
|
The suggestion was given to disable passing the output via a socket to have higher performance that via the protocol by adding
|
||
|
|
|
||
|
|
```
|
||
|
|
(setf slynk:*use-dedicated-output-stream* nil)
|
||
|
|
```
|
||
|
|
|
||
|
|
Since I rather have something working that it being high performant not-working I followed the suggestion which fixed the issue:
|
||
|
|
|
||
|
|
|
||
|
|
```
