The On Center Handling analysis requires two user defined variable statements in the dataset. These variables are used to store the maximum lateral acceleration recorded during the first and second stage of the oncenter analysis. Based on these recorded lateral accelerations and the user specified steering wheel input for the first two stages of the analysis, the necessary steering wheel angle required to produce the user specified lateral acceleration can be determined based on a straight line equation. The variable statements extract the necessary output from a user request. Extracting Request Output Through Variable Statements explains how a request output can be assigned to a variable statement.

The syntax for the variable statements are as follows:
