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.
Kind regards
Claus Holst

[EpiData-list] adding variables to existing rec. file

Can anyone give me advice on how to add a variable to an existing rec file 
when data entry during an ongoing cohort study without loosing the 
recorded data entries?
