Hi all,
I've got an issue with the following. It used to work in the past, but doesn't do so anymore. I want to estimate a panel model for a sub-sample dataset. I am using current cvs on linux.

open abdata.gdt

# Restriction for which panel structure remains
smpl YEAR > 1977 --restrict
smpl full

# Restriction for which panel structure doesn't remain
# -> Undated dataset
smpl YEAR > 1977 && EMP > 40 --restrict

# Redefinition to panel structure is not allowed acc. to gretl

setobs unit YEAR --panel-vars

<\hans>

Any hints what's wrong here?
