For even more head scratching, try this:

clear all

forvalues i=1/6 {
set obs 10
gen y = 1.2x + `i'

something obvious or a syntax that I don't recognize.  I'm using version
10.1 MP on a PC.  I've run this on three different PCs and get the same
result.  Why doesn't the generate command for "y" give an error?  The
-generate- command gives errors for y1, y2, and y3.  Also, I don't
understand the output for -tab- command for "y".  Is there some syntax
that I'm not aware of?
