You can add new types with a module. For tcl scripts, you can use the "XTRA" type to add whatever you want. See setuser and getuser in tcl-commands.doc.
I know about the XTRA type, but I mean about a completly new info type, for example to add a multipale infot type(like HOSTS) that his entery will be for example "typi".
So when i'll do "setuser <handle> typi hello"
and "setuser <handle> typi bye" it will add "hello" and "bye" to the userfile for the handle I entered.
Is it possible to do it?
The functions to deal with this are provided by C.
It involves creating a function to take th einput and store it when the data is read, and function that will create the output format when writing to the userfile.
This isn't, and will doubtfully ever be provided in Tcl.
