All, Suppose I have a number of lines in a latex file like this:
\backans{If $x=y^{2n}$ and $z=y^{3n}_{11}$, then we can substitute to find a solution.} I'd like to scan the file and replace all of these with this format: \begin{answer} If $x=y^{2n}$ and $z=y^{3n}_{11}$, then we can substitute to find a solution. \end{answer} I'm looking for suggestions as to how to make this change with my perl script. I am puzzled by the use of nested braces and how I can be sure I've got everything between the opening and closing brace. Thanks. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
