A Regular Expression Matcher Code Listing

In the code listing for the matchhere function in the chapter "A Regular Expression Matcher", a line reads:

returnmatchhere(regexp+1, text+1);

. I believe that the correct line is:

return matchhere(regexp+1, text+1);

Note from the Author or Editor:
The reader is correct. There should be a space after the return keyword. This problem exists only in the Safari version, not the printed book.

In the method "isHexDigit" the line:

5th paragraph 2nd to last complete sentence on page

Sentence reads "... has an opcode of Ldc_R8, which will load an 8-bit real (that is, a floating-point number) on the stack.

I believe 8-bit should be 8-byte.

Note from the Author or Editor:
The reader is correct. Please change "8-bit" to "8-byte" on p. 121

In the following sentence:

Based on the definition of the struct usb_interface recently shown,
the dev variable is probably placed 16 bytes into the structure on a
32-bit processor.

Please change 16 to 14.

2nd paragraph

It should be -1549758592 mod 32 as the number of slots is 32 and -1549758592 mod 31 is 11 not 0 (mod 32 is 0).

Note from the Author or Editor:
lease change "mod 31" to "mod 32" as the reader indicated.

A parenthesis was dropped in a cast.

Statement

should be

node = XPathAPI.selectSingleNode(root, (String)xpathvals.next());

Note from the Author or Editor:
The reader is correct. Please make the requested change.

"Simon Peyton Jones" is incorrectly alphabetized. His last name is "Peyton Jones" not "Jones". The same mistake also occurs in the index.
