?fullpath(curdir()) >?fullpath(sys(5)+sys(2003))The issue is SYS(5) and UNCs; I don't have all my notes here, but SYS(5) behaves poorly in some network situations where you're sitting on an unmapped UNC. SYS(2003) is always fully qualified; I'm arguing against the use of SYS(5) at all, and if you're simply getting the current directory on the current drive, FULLPATH(CURDIR()) is more human-readable than FULLPATH(SYS(2003)) and more self documenting, and both work equally well (yeah, why should this matter?) I'd argue just as vehemently against SYS(5)+CURDIR()...
