T Book Errata

[Stephen Slade <slade-stephen@YALE.ARPA>]

Gentle readers:

It's dirty laundry time.  Here is a list of errata for the book:

        "The T Programming Language: A Dialect of LISP"
        Stephen Slade, 1987, Prentice-Hall.

I am confident that the diligent reader can uncover additional 
egregious errors.  Please let me know of same.

chapter 1
p 4     line 5
    "several other LISP dialects" should read "Common LISP"

chapter 2
p 11    line 5
    extra prompt ">"  should be deleted

chapter 3 
p 51    first example
    "top-level list..." should read     "first top-level list..."

p 53    bottom of page
    second "(define x ... 'd)"  should be "(define y ... 'd)"

chapter 4
p 60    epigraph
    "(1986)"            should read   "(1987)"

chapter 9
p 152   middle of page
    remove the "whale" of type "fish"
    (this does not affect the execution of the code, but may be confusing)

p 157   middle of page
        "There are no iteration arguments in this example."  should read
        "count is the single iteration argument in this example."

p 164   "'error-in-sub-binary"  should read
        "'error-in-process-node"

chapter 11 (macros)

p 211   This definition of my-block0 has a hole in it:

    >(lset rest 6)
    6
    >(my-block0 rest 4 5)
    #{procedure 4}

        See answers to this exercise for better solutions.

chapter 12 (structures)

p 225   middle third of page
    "T"                 should read     "#t"    (3 occurrences)

pp 239, 250, 252
        object examples have print methods which use "stream" as an identifier
        for a "port".  This is not wrong, merely confusing.

            ((print self stream)
             (format stream ...

        should read

            ((print self port)
             (format port ...
