Hello again,
I am trying to convert data to account for inflation. 
I have an excel (or variable, whichever is better) with the cumulative inflation for every quarter between 1980 and 1990 (my period of interest) and in gretl data about salaries that contain, amongst else, the wage, and the year and the quarter in which the sample was taken.
What I want to do is to multiply all the wages from samples from quarter i, year j with the right inflation factor.
Any hints on how to do this?

thanks very much,
Raz
