David,

Might I suggest that our developer list is not the appropriate place to teach you how to use Linux nor to program in Scheme? This list is not for newbies, sorry.

As I told you before, the PATH environment variable is used by the shell to find executable files. It is the matter of having the hello.world file executable and beginning with #!/usr/bin/guile that allows you to type its name directly from the command line; including your Documents directory in $PATH just saves you from having to type out the path. Try that instead:
  Documents/hello.world
and see if you get the same error.

Don't reply here, nor to me personally. Find resources appropriate to what you need to learn. An adult-education class on Linux and/or beginning programming would be an excellent option.

Regards,
John Ralls
