question of how to properly dispose of a message

Hello all,

I need a simple clarification if anyone could help me.

I have some messages that I want to route to one thread if a patient name is … oh say…’John’

I want to route all other patients not named ‘John’ to a different thread.

I have my tcl pre-procs written to filter by name, but my question is…just how do I ‘kill/suspend’ the message?

I can do ‘lappend dispList “KILL $mh”‘ to the ones that I don’t want to go to that thread, and that works.

However…I can also not do lappend dispList “KILL $mh”, but instead just say ‘return “”‘

Both of these provide the results that I want…but I don’t know which way is correct.

Could someone please let me know, and also let me know why one would be incorrect?

I don’t want to accidentally kill something that I am not supposed to, and I also don’t want to leave lingering messages out there….and I am not sure if one of my killing methods results in either of those situations.

Thanks,

Julie
