on me: "The object 1, passed as an argument to safe-car, is not a pair" 22:40:09 what's odd though, when I go in to the debugger, this is happening from the following: (cadr pair) 22:40:23 and down at the bottom it says: pair = (d . 1) 22:40:35 GlenK: if `pair` is actually a pair, then `cadr` will fail on it. You want `cdr`. 22:40:52 (err, a pair that has a non-pair as its cdr that is) 22:40:54 There's no cadr in (d . 1) 22:40:56 (such as (d . 1)) 22:40:58 Only a car and a cdr. 22:41:02 (cdr '(d . 1)) == 1 22:41:10 (car 1) is an error. 22:41:17 therefore (cadr '(d . 1)) is an error. 22:41:34 sounds like I'm an idiot then. cheers. =) 22:41:42 Try: (a . (d . 1)) instead; (cadr '(a . (d. 1))) == d 22:42:04 Since (a . (d . 1)) == (a d . 1) and cadr returns the second element of the list, ie. d. 22:42:25 (but this dotted-list (a d . 1) has no third element). 22:42:44 -!- annodomini [~lambda@wikipedia/lambda] has quit [Quit: annodomini] 22:44:00 hmm, or actually this isn't my fault? scheme has changed since sicp was written? have a look at make-leaf-set from here: 22:44:04 http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-4.html#%_toc_%_sec_Temp_261 22:44:05 http://tinyurl.com/l69w79k 22:44:16 that's where my cadr came from 22:44:27 Hmm, Neil of neil/charterm isn't around here is he? 22:44:39 Well in any case, I've sent an email. 22:46:21 -!- tenq is now known as tenq|away 22:46:31 And my "solution" to remove the -f flag from stty makes it work, or so it seems. 22:46:33 So I'm good. 22:48:34 -!- tenq|away is now known as tenq 22:50:43 Ok, apparently (charterm-screen-size) returns two values.
