Having the option to append to a spool file would be very useful to many. There are many times, where one want to spool some commands, then turn spool off for others, then later start to spool other commands and so on. Now it is not possible to do, without manually going to the command line, saving the old file somewhere and starting over, then later merge the files manually again. Ideally, user should have an option when starting spool to either overwrite the spool file if it exists, or to append to it. This gives most flexibility. But if this is not possible, I'd go for the default being to append to the file if it exists. Thanks --Nasser > On Tue, Jan 23, 2018 at 2:07 PM, 'Nasser M.
