Levels can be combined together into a level description. It's like a bit-mask. Separate the levels with commas. You can turn off a level by prefixing it with a hyphen (“-”). Turning off a level is usually done after the ALL level (see below).
|MSGS||Only the MSGS level|
|MSGS,PUBLICS||All MSGS and all PUBLICS, but nothing else|
|MSGS,PUBLICS,-PUBLICS||Only the MSGS level (PUBLICS got turned off)|
|ALL||Every level shown below|
|ALL,-MSGS||Every level shown below but not the MSGS level|
Except for the DCCS level, each server refnum has its own distinct set of levels. This means if you have 4 servers, then each of those 4 servers has its own PUBLICS level, and the PUBLICS level on one server does not correspond to the PUBLICS level on another server.
Each window in the client is associated with a server, and each window claims one or more levels on behalf of that server. This is how the client decides which window your output will go to: all output from the client has a level associated with it, and the client looks for the window associated with that server that claims that level, and puts the output there. (Oh, yes, I know there are exceptions to this…)
The DCC level is global, because DCCs do not belong to a server. So only one window in the entire client is supposed to have the DCC level at a time. This window should receive all output regarding DCC activity.
The client supports dyanmic level creation, but not dynamic level deletion. You can create your own levels, or create alias names for existing levels using the levelctl function.
Remember that levels are just a bitmask. Each bit only exists once, but each bit has one or more names.
