The following commands are currently implemented. Four commands are borrowed from Tk4.0, because they are usefull in pvmsh too.
During execution of command, only data that matches tid and msgtag can be received, So the recv command doesn't need to specify it any more. Inside the command there are 3 macro's that can be used to find out additional information about the received data:
If command is the empty string, the binding is deleted. If the command is missing, the currently bound command is returned.
The data will be received from the channel that currently is open. Generally this is specified by the bind command.
The spawn command returns a list of tid's that later can be used in other commands. An error is genereted if no processes can be spawned.
