Hi Nala Ginrut,

Thanks for your reply.

I suspect I expressed myself poorly. (execlp "ls" "") replaces guile with "ls", which lists my files and returns me to the shell.

What is some-function, where some-function works like this:

(some-function "ls")
-> "/bin/ls"  (I'd settle for #t")
(some-function "asdfasdf")
-> #f

I thought that execl or its friends would be the way to answer that question...
