PRESCRIPT=Scriptname/OFF

This specifies the name of an ARexx script to run before each image is rendered. This can be used to produce only some of the frames and control the movement and colour of the images.

The default script is Rexx/Prescript.

The version supplied does nothing.

Set to OFF to run no script.

It can be changed using the menu item (if reqtools.library is available), a requester is displayed allowing the input of the value.
