 19.6 Executing Scheme code
 ==========================
 
 Once you have an interpreter running, you can ask it to evaluate Scheme
 code.  There are two calls that implement this:
 
  -- Function: SCM gh_eval_str (char *SCHEME_CODE)
      This asks the interpreter to evaluate a single string of Scheme
      code, and returns the result of the last expression evaluated.
 
      Note that the line of code in SCHEME_CODE must be a well formed
      Scheme expression.  If you have many lines of code before you
      balance parentheses, you must either concatenate them into one
      string, or use `gh_eval_file()'.
 
  -- Function: SCM gh_eval_file (char *FNAME)
  -- Function: SCM gh_load (char *FNAME)
      `gh_eval_file' is completely analogous to `gh_eval_str()', except
      that a whole file is evaluated instead of a string.
      `gh_eval_file' returns `SCM_UNSPECIFIED'.
 
      `gh_load' is identical to `gh_eval_file' (it's a macro that calls
      `gh_eval_file' on its argument).  It is provided to start making
      the `gh_' interface match the R5RS Scheme procedures closely.
