Does not even need an actual "x":


*******
clear
set obs 10
gen y = 1.2x+3
*******

It does, however, need an addition afterwards.

I guess Kieran`s guess re hexadecimal was right...

But then it seems to take 12 and multiply by 6 to get 72.  This is the kind
of arithmetic my students sometimes do... :-)

When I do this, y = 72 for all cases.  So 1.2x must be getting 
interpreted as 1.2 * 10 = 12.  I don't know why, but just follow 
Martin's advice and make it

gen y = 1.2*x + 6

Maybe this is a "feature" but if so it doesn't seem like a good one, 
since this could be an easy mistake to make.
