I have a databases where each case has several data points from 3 different data collection points in time.  I have very little missing data, ie just a couple of variables for a couple of cases.  However, I would like to carry the baseline value forward to the missing data point at the later time point.  Also, I would like to do this in such a way that I can log it in the syntax file and have it saved for checking and reproducing. Thanks for any assistance
