How to extend the viewing time for the displaced structure

[GunAndRose]

Hi, all
We have the file of "RCFrameDisplay.tcl" in the user manual as below when we want to view the displaced srtucture:

recorder display Dispshape 50 50 600 600 -wipe
vrp 288.0 150.0 0
vup 0 10 0
vpn 0 0 10

prp 0 0 1000
viewWindow -400 400 -400 400
plane 0 150
projection 0

port -1 1 -1 1
fill 5

display 1 0 10

My problem is the figure shown on the screen only lasted for 1 sec or so. Can I change some parameters above or introduce some new command to extend the viewing time for the displaced structure?

Thank you very much.
