Thanks for replying. It seems that the stackoverflow was talking about making changes to a file's title, whereas I'm trying to have Excel write the first two bytes in a unicode file as FF EE and not FF 00 FE 00.
A unicode file's first two bytes tell what type of file it is... and FF FE is a Unicode UTF-16 Little Endian file. I'm not an expert by any means... just trying to get my son's code working properly.
After the file is written by Excel, I have to load it into Notepad and delete the first 2 characters that show up at the start of the file, and then save it. This removes the FF 00 FE 00 and replaces them with FF FE.
