> Play Values

  Certain scipts require certain changes in the preferences to
  produce the desired result but having to change eValid's preference
  setting everytime a unique script is run would basically increase
  the amount of work to be done and makes it prone to human error from
  changing the preferences every so often.

  eValid has an available script command which can be hand edited
  within the script to automatically change the settings temporarily
  while the specific script is being executed. Once the playback is
  stopped, eValid reverts to the original settings in the preferences
  menu.

  Adding a "PlayValue" command is as easy as opening the Script Dialog
  Box, selecting the "Extrinsic Commands", and selcting "Play Value" as
  the option.

  The syntax for the PlayValue command would be:

  # PlayValue _P? [val] - set a playback value
  # (see eValid documentation for details)
  PlayValue _P
