Issues reshaping data

However, going the other way has me stumped with this type of data. My data is set up, roughly,

Word97 launches but still cannot save or load
Dear friends: Thanks to Ekkehard, I found out how to launch Word97. I went to the .wine/drive_c directory and then (using quotes around "Program Files" and "Microsoft Office") I cd's to where Winword.exe was and then typed, within this subdirectory: wine WINWORD.EXE. That launched Word97 at last. But when I try to save a document, all I get is the first letter of the file

So if they search for (in my case) transferaze which has no matches I can get back an array like this [''transferase''] ?
