My main proc calls some back-end procs so the other developers here don’t have to be bothered with the details. In certain cases id like to error out the message.
In order to do this the only thing you would really need to do its to global the displist. However i have no real way of returning the displist from a sub proc, as returning would simply exit from that proc and resume running the calling proc.
I see in tcl 8.5.7 documentation the return function has a parameter for level. Im assuming this would work for me, i could simply dictate the level would be at 2 instead of the default 1. However in tcl 8.4 (which CL 5.7 uses and we are running) i dont see that same parameter.
Does anyone know of a way to work around this in 8.4? If not, do we know when CL will move to 8.5.7 or greater?
