Dear all,
.csv file

var1,var2,var3
21,“male”,2
22,“female”,3
23,“male”,4

is read ok, e.g.
          var1

1           21
2           22
3           23

          var2

1       “male”
2     “female”
3       “male”
 
For, example
series var4 = var2 + 5
is ok

But gretl\File\Save data,
gretl:save file\save
crashes Gretl
