Hello, I'm a starter with Gretl, and I have to basic questions: 1) I have two variable: salary and women (1=women,o=men). Hos can I create a variable that is salary if the individual is a men but a missing observation if the individual is a women? genr WW = salary if women= 0 AND NA if women=1 (I know that this is not the syntax not even the instructions of Greatl but I need help asap to start with Gretl) 2) I Would like to export data from Grertl to Excel. What is the quickest way to do it? Thank very much in advance
