These are errors in the first printing of "Programming Languages: An Interpreter-based Approach," by Sam Kamin, Addison-Wesley, 1990. Included are only the substantive errors, not simple typos or merely aesthetic corrections. Errors in the second printing (a subset of those in first printing) are listed separately below. (For reporting a number of these typos, thanks to: Tim Budd, Chris Van Wyk.) Errors in the table of contents and, especially, the index are too numerous to list. The main problem in the index is that page numbers in the appendices are almost all too high, by an average of two pages. Read "->" as "should be changed to". One case of this is `-> ""', which means "should be deleted". p. vi, "Overview" section, l. 1: "?" -> "1979" p. 14, l. -11: "FUNDEF" -> "f: FUNDEF" p. 32, l. -5: "Coli" -> "coli" p. 59, "Further reading" section, last line: "Reingold [1988]" -> "Reingold and Reingold [1988]" p. 62, l. 2: "The interpreter" -> "The new version of the meta-circular interpreter" p. 62, l. 5: "programmed in Exercise 10" -> "" p. 68, l. 8: "vector V," -> "vector V, where \oplus is any primitive dyadic operation," p. 71, l. -5: remove one closing parenthesis at end of line p. 98, l. 10: "(page 15)" -> "(page 13)" p. 110, section 4.3, l. 1: "??" -> "C" p. 125, last line of text: "e2) e1)" -> "e2)) e1)" p. 126, line "(sum (f (car l)) (loop (cdr l))...)": delete three closing parentheses p. 139, l. -14, -12, -10: on each line, second arrow show be star, e.g. l. -10: -> (int \arrow bool) * int list \arrow bool p. 148, para. 2, l. 3: "Sethi [1988]" -> "Sethi [1989]" p. 149, l. -5: "(gcd 3 5)" -> "(gcd 9 11)" p. 156, l. 6: "(find-val pred (cdr ilis))))" -> "(find-val pred (cdr ilis) (+1 100))))" p. 162, l. -3 (of text): "a_i" -> "x_i" p. 176, l. 11: "subsets" -> "gensubsets" (twice) p. 177, l. 13: "find" -> "find-val" p. 182, l. 3-6: "CADR" -> "CAR" p. 186, l. 9: "(f x y)" -> "e" p. 199, para. 2, l. -3: "In fact" -> "Furthermore, if we restore the restriction that the path remain entirely within the first quadrant" p. 285, l. -15: "List" -> "SequenceableCollection" p. 311, l. -11: "(release-terminal THELAB self)" -> "(release-terminal THELAB status)" p. 345, l. 6: "(from:to:by: n n+km k)" -> "(from:to:by: n n+km m)" p. 417, second box: "ALLOC 2,rv" -> "ALLOC 2" p. 550, l. -12: "ord(op)" -> "ord(op)+1" p. 563, l. -17: "ord(op)" -> "ord(op)+1" p. 616, middle: "[1988] R.

This list is a subset of the list above: p. 98: l. 10: "page 15" -> "page 13" lines -9, -8 use a notation for vector x that's only defined on p. 254 p. 156: l. 6: "(find-val pred (cdr ilis))" -> "(find-val pred (cdr ilis) (+1 100))" p. 163: l. 9: "page 33" -> "page 31" p. 176, l. 11: "subsets" -> "gensubsets" p. 285, l. -15: "List" -> "SequenceableCollection" p. 311, l. -11: "(release-terminal THELAB self)" -> "(release-terminal THELAB status)"
