As such it was expected that people running the sample would prefer a message written to the screen rather than hidden away in some error log somewhere. This does presuppose though that your channels are running in a command window eg. runmqchl. In the general case though channel exits should not assume that STDOUT or STDIN are pointing anywhere meaningful. In many cases they point to the NULL device for reasons I won't go into. If you deploy an exit in production I would expect it to write it's error messages to a 'well-known' place, usually an error file, the syslog or NT event log or similar. Cheers, P.
