statevar

The statevar command manipulates state variables. State variables are varialbes that are write protected while a run is active. They are intended to contain information that documents the conditions of a run. For example, a statevar named beam might have the specifications of the beam during the run. State variables are logged to the event stream when the run becomes active. The statevar command allows you to:

• Create a new state variable.

  	        %  statevar name
  	    

  Creates a new state variable: name.
• List the set of state variables defined whose names match a glob pattern.

  	        %  statevar -list ?glob-pattern?
  	    

  Lists the set of state variables whose names match the pattern glob-pattern. Note that if this optional parameter is not supplied, all statevars will be listed.
• Delete a state variable.

  	        %  statevar -delete varname
