Yes, I am trying to replace some functions as seamlessly as reasonably possible and for that to work so other code could use them presumably the new ones have to be black box replacements for the old ones.

Thanks for the info and help. I may have to look at writing a message wrapper in Sys RPL, if it's possible to set the command name that way.
