Although readLines is normally to be preferred (in R and S-PLUS 6: it's a lot faster for a start), we've fixed this so that scan() in R 1.3.1 will give a warning R 1.4.0 will allow unlimited lines (unlimited by R, that is). As ever, previews are in r-patched and r-devel (tar bundles/rysnc) respectively. The 1.4.0 version needed quite a lot of re-writing of code, too much for a patch release.
