17.2 Creating a server instance

Before issuing any plotting command, one shall have started the graphic server to which all plotting will be directed.
In principle one can create several instances of the same kind of server. Each instance is characterized by a sequence number.

One may then direct plotting to the wished server issuing command

xasset plotter servinst
The default plotter is xw1.
Beware that switching among plotting server uses a single graphics environment which is not reset when one switches back !
The command used to start a new instance of a given type of server is
createserver [server instance {extraargs} 
where the additional extraargs are currently defined only for the X-11 server as: A server is normally used from a single session (i.e. is associated with the terminal window from where it was started). See however directions for using the same server from more than one session.
