You are bound to be confused if you read SICP and practice in a lisp-2 (as the kind with separate name spaces for variables and functions are called). Perhaps you should get an actual scheme implementation to play with? | |

| Aug 14, 2015 at 11:00 | comment | added | Luis404 | do you mean this: sum 'inc-test 1 'inc-test 10 ??? got this error: usage: sum : (TERM A NEXT B) | |

Emacs Lisp has two namesapces for functions and for variables. This means that inc-test in your last example is used as a variable, but is not defined as a variable (it is a function). You need to pass either a symbol or a function reference to funcall. Hence one way of fixing your code is to pass it 'inc-test instead of inc-test (note the quote).
