(guile.info.gz) The REPL

 
 14.3.2 Using the Guile REPL
 ---------------------------
 
 If you start Guile without specifying a particular program for it to
 execute, Guile enters its standard Read Evaluate Print Loop -- or
 "REPL" for short.  In this mode, Guile repeatedly reads in the next
 Scheme expression that the user types, evaluates it, and prints the
 resulting value.
 
    The REPL is a useful mechanism for exploring the evaluation behaviour
 described in the previous subsection.  If you type `string-append', for
 example, the REPL replies `#<primitive-procedure string-append>',
 illustrating the relationship between the variable `string-append' and
 the procedure value stored in that variable.
 
    In this manual, the notation => is used to mean "evaluates to".
 Wherever you see an example of the form
 
      EXPRESSION
      =>
      RESULT
 
 feel free to try it out yourself by typing EXPRESSION into the REPL and
 checking that it gives the expected RESULT.
