Except in functions which accept either a filename or a filehandle, such as the file test operators, or truncate... $ cat testcase use FileHandle; use POSIX; $f = new FileHandle '/tmp/foo', 'w'; $f->autoflush; print $f "file handles in Perl are perfectly horrid"; truncate $f, 32 or warn "truncate failed: $!\n"; $ perl5.001l testcase truncate failed: No such file or directory According to trace, this actually calls truncate ("FileHandle=GLOB(0xbf368)", 32) :-( Tim. -- Tim Goodwin | "If you're used to paint-by-number, a blank canvas Public IP Exchange | can be unsettling at first." -- Larry Wall
