# old old TEX files

The following is an old code. I have many others, but this is the shortest one. It was certainly compiling at the time it was written. Is there a way to recover it in pdf format? Thanks

• Apart from the need to track down mathdef.sty I don't see an issue here (LaTeX2e has a LaTeX2.09 compatibility system). – Joseph Wright Jan 27 '16 at 20:24

• Fortunately they didn't use \today so we know how old it is. – Sigur Jan 27 '16 at 20:29
• @ClaudioCardella there is a file of that name in the zip file here storage.googleapis.com/google-code-archive-downloads/v2/… and that's the only one google found, so it may be that file. but if mathdef.sty` was just your local math definitions from that time and never public then you need to find (or recreate) them. But basically latex is designed so that 30 year old documents still work so i would not expect any problems, – David Carlisle Jan 27 '16 at 20:45
