Hi Pihilipp, Not to difficult: Revise the qes file with the new variable Next time you open the rec file it will notice that the qes file has changed (must be in the same directory) and will offer to update the rec file. Accept this - no data are lost If neccesary you can then also revise the chk file with relevant info about the new variable. Voila. Kind regards Claus Holst Copenhagen
