Hello, I have just checked with SBCL, and here is where the error with *READ-DEFAULT-FLOAT-FORMAT* occurs, probably because of threads. Also, your modifications of slime-start-and-load do not work with SBCL. I.e. after doing (slime-start-and-load (concat *femlisp-root* "start.lisp") "FL.APPLICATION") I get ... CL-USER> CL-USER> *READ-DEFAULT-FLOAT-FORMAT* SINGLE-FLOAT When I then set the default format manually in the REPL, it is reset by `M-x slime'. CL-USER> (setq *READ-DEFAULT-FLOAT-FORMAT* 'DOUBLE-FLOAT) DOUBLE-FLOAT CL-USER> *READ-DEFAULT-FLOAT-FORMAT* DOUBLE-FLOAT CL-USER> [ I have executed `M-x slime' here] CL-USER> *READ-DEFAULT-FLOAT-FORMAT* SINGLE-FLOAT CL-USER> Yours, Nicolas.

1. If Slime is not already running, the load command is not executed.
2. If Slime is already running, Femlisp is loaded, but the package is not set.
Can someone tell me how I can achieve my goal?
Yes, this is bit more difficult because most of the commands work asynchronously. I changed slime-start-and-load a bit so that it should be usable for your needs.
In general If you need commands of this sort, it's usually the easiest to write a small CL function for the job, so that Emacs can make a single RPC and doesn't need so much synchronization.
PS: Another problem is that executing (slime) apparently sets back some variables, e.g. *READ-DEFAULT-FLOAT-FORMAT* which I have set to DOUBLE-FLOAT when loading Femlisp. Why is that?
Can't help you here without more details. Which Lisp are you using? Which communication style? Are threads involved? We don't set *READ-DEFAULT-FLOAT-FORMAT* explicit, but there's always the possibility for bug and that we used WITH-STANDARD-IO-SYNTAX in a wrong place.
Helmut.
