something like this should work: (execute-with-environment "XX2=LOL" "/tmp/mybin") working example: guile -c '(import (sph process)) (execute-with-environment (list "XX2=LOL") "/usr/bin/echo" "test")' but this is using the system call "execve", which leads to the whole guile process being replaced by the specified program. (execve syscall reference: http://man7.org/linux/man-pages/man2/execve.2.html) "process-create" creates a new parallel process --- (define pid (process-create (lambda () ;this will be executed in a completely cloned new process in the background (execute-with-environment "XX2=LOL" "/tmp/mybin")))) ;now, still in the guile process, send a signal to the new process (kill pid SIGINT) --- now what happens is that a new process is created by cloning, and is then immediately replaced by your program. as far as i know this is the only way on linux or similar systems to archieve this. for storing values in a record it would probably be best to use a record setter procedure. the library supports setting fields by symbolic name, but that is slower. in general, as a sidenote, a record like this differs from an association list for example, in that the keys are not stored inside the data-structure, but separately: the "layout" stores the field names and the positions of where the field values are stored in the records. example: --- (define myrec (make-record-layout (quote (pid env)))) (define-record-accessors myrec (myrec-pid (quote pid)) (myrec-env (quote env))) (define-record-setters myrec (myrec-pid-set! (quote pid)) (myrec-env-set! (quote env))) ;two different ways to create a record (define a (record myrec pid "LOL")) (define b (make-record myrec)) (myrec-pid a) (myrec-pid-set! a 3) (myrec-env-set! b 2) --- EOM
