Hi, I need to create a variable that take the lead value of another variable, I found in internet that I could use merge to do this (Also expanc but I have no license sas ets):
keep=Fecha 'nombre comprador'n 'rut comprador'n 'nombre vendedor'n 'rut vendedor'n Instrumento Liq Cantidad Precio Tasa
Monto Valor Comisión 'T/C'n 'Codigo Folio'n Mvto 'Proc#'n Mon Bol Hora Observación Tipo Tipi Rutc Rutv SecuenciaC SecuenciaV
In the internet example, they put "keep=x" and the X variable keeps the values and doesn't start in the second observation, but when I do this, all variables start in the second observation.
cruz2 is the variable that have the lead value of cruz1. So, I get the lead value, but rest of my variables are wrong because the start in the second observation . Anybody could help me please?

I could solve it!
The rest of variables are not important. with that code could keep the 1first values of all the variables and also get the lead value of cruz1 for cruz2.
The only problem is that i don't understand why, maybe it'll be helpfull if someone could explain the code.
