For example, a-b will be interpreted as a name, but a - b and a -b will be interpreted as arithmetic operations." Change "operations" to "expressions". The phrase "could otherwise" is vague. For instance, consider the query: a- b There's only one way to derive these characters from Expr (the "a minus b" way). That is, there isn't a legal way to interpret the '-' as part of the previous token. So one could say that the "could otherwise be interpreted" clause does not hold, and conclude that the hyphen needn't be preceded by whitespace. This is presumably not what you want, since the first example in A.2.2.1 says that foo- foo is a syntax error. It might suffice to tack on something like "See section [blah] for full details regarding the use of whitespace." which at least conveys that the sentences in question don't give a complete statement. Maybe put the sentences in a Note. 4406 1 chamberl 2005-07-01 00:39:45 +0000 Michael, Thanks for your thorough reading and comments. Since you have labeled these suggestions as editorial, I have exercised some discretion and applied them where I found them helpful. Regards, Don Chamberlin
