Stata has no concept of columns or rows, except for matrices. However, let's presume that you mean variables and observations. You don't say what is in the gaps. If it's missing numeric values, . gen C = max(A, B) will suffice, as indeed will -min(A, B)-. Either will do because both -max()- and -min()- ignore missings unless all their arguments are missing. Nick n.j.cox@durham.ac.uk Mihai-Andrei Popescu-Greaca Here a question regarding data management: How can I combine the columns A & B (only one value/row) together to form column C?
