Trying to write data out to an excel file, and it works fine with one exception. If someone has the file open, then (setq file (open "f:\my path\log.xls" "a")) returns an error (stringp nil). That's expected, and I'm OK with it. Is there a way to silence the error at the command line and just exit quietly? I'm having a lot of trouble with it. I don't care if it doesn't work all the time, I just don't want to see it. TIA
