[Gretl-users] stata REPLACE command

Hi folks. What is the GRETL translation of the command "REPLACE ... IF" in STATA? Specifically, in STATA I would use REPLACE W=. IF L==0 to change my data in STATA (making the variable W missing if the variable L is zero). Messing around in GRETL I have come up with the following 3 lines: smpl L=0 --restrict genr W=NA smpl --full Is there a simpler/briefer way to do this is GRETL? Maybe using IF? Thanks for any suggestions -- jim irwin (economic historian, moving from STATA to GRETL).
