I'm sorry, I should have made my question more clear. I'm writing to a file with a ".doc. extension, and I was wondering if it was possible to set the font in word to "Arial".
I can write to the file but if I change the font after the fact, then my formatting is lost.
Anonymous Monk,
There have been many nodes here on creating Word documents and modifying existing Word documents. The consensus, as best I can tell, is that you can't easily/effectively create Word documents in Perl because the standards are terrible and vary from version to version. You can check Super Search to see if I missed something. Unless you have found a module I do not know about, it sounds like what you are doing is just opening a file with a .doc extension and writing regular text to it. There is no such thing as changing the font in this regard.
The alternative is to create a Rich Text Formatted file that can be opened by Word and then automatically converted. This will certainly allow you to change your font. See RTF::Document for details.
