ISHOLD

 

 Return 1 if hold is on.

  ISHOLD returns 1 if hold is on, and 0 if it is off.

  When HOLD10XXCU2 is ON, the current plot and all axis properties

  are held so that subsequent graphing commands add to the 

  existing graph.

 

 

  Hold on means the NextPlot property of both figure

  and axes is set to "add".
