set imprun
set imprun script-name
This command sets up automatic execution of a grads script before
every display command.
Examples
This script is typically used to set an option that by default
gets reset after each display command, for example:
set grads off
Usage Notes
You can issue any grads command from this script, but the
interactions are not always clear. For example, if you issue a display command
from this script, you could enter an infinite recursion loop.
The argument to the script is the expression from the display command.
