Actually, most of this is me rather than Saikat.

I use use.value.labels=TRUE most of the time. The main point of is that it is quite a lot faster for large files, especially if you are going to use only a few of the variables. I think Brian Ripley spoke up in favour of it for this reason last time the issue was raised.

The reason I made trim.factor.names=FALSE the default was backwards compatibility, but it probably makes sense to switch it at some point.

Incidentally, PSPP (the original source of the code) now has a version that reads long variable names from post-version 12 SPSS files. This confirms that the "unrecognised record type 7, subtype 13" message really is due to long variable names and so is harmless. It also means that anyone who wants long variable names badly enough could work out a patch.
