To generate a log variable in Eviews, you can use the natural logarithm function. In Eviews, you can create a new series by taking the natural logarithm of an existing series. 

For example, if you have a series named "X" and you want to create a new series named "log_X" that contains the natural logarithm of "X", you can use the following command:

$$log\_X = @log(X)$$

This command will create a new series named "log_X" that contains the natural logarithm of the values in the series "X".
