[Gretl-users] genr, vs scalar and series

Hi all, What is the preferred use of these in hansl? I've started using scalar for all scalar computations (but in any old code I used genr); sometimes I use series instead of genr to generate new variables. I do realize that series will generate a series from a scalar. For instance, which is the preferred usage: open engel set seed 3213789 loop 100 --progressive --quiet series u = normal(0,88) series y1= 80+10*income+u ols y1 const income endloop or open engel set seed 3213789 loop 100 --progressive --quiet genr u = normal(0,88) genr y1= 80+10*income+u ols y1 const income endloop also suppose I want to print or store a scalar, which of these is preferred way to generate the scalar? scalar b = $coeff(income) genr b = $coeff(income) I'm trying to finish the updated version of my gretl book and my code needs some tidying up. Looking at it now, it is pretty much a mess. It seems I've mixed the usage of these up throughout and I'd like to know the preferred way before I hack my way back through a thousand lines of code .....
