Like so?

clear
set mo off
set obs 100
loc mlt = 1
forval i = 1(1)100 {
	g var`i' = _n
	replace var`i' = var`i' * `mlt'
	loc mlt = `mlt' + 1
	}

stack var*, into(nvar)

Hello,

I am at the end of my tether with Stata 10 and was hoping someone could help me:

I have a dataset which I am trying to manipulate:

Assuming the following variable:

1
2
3
4
5
6
7
8

I am trying to create a variable which will show:

1*1
1*2
1*3
1*4
.
.
.
2*1
2*2
2*3
2*4
.
.
.
...and so on.


I really don't know where to look as I can't think what this mathematical operation would be called. Maybe I'm just dim.

Many thanks,

Tim Burnett
