I don't think you understood what I was trying to say.
Octal \042 represents the double-quote character. There is no reason to enter the character as octal. You could literally have typed the quote character. And if you did so, you would not experience the problem. In the notebook, replace:
=93\042 =93
with
=93\=94 =93
The MathGroup post corrupted what I typed last time, so to clarify, that's double-quote backslash double-quote space double-quote, or in other words, the string that results from the following command:
FromCharacterCode[{34, 32}]
