For even more head scratching, try this:

clear all

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

I have a question which I hope merely reflects that I'm missing 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?

What am I missing here?

. clear
. set obs 10
obs was 0, now 10

. range x 1 10
. range t 1 10
. range w 1 10

. gen y = 1.2x + 6   <----- why isn't there an error here?

. gen y1 = 1.2t + 6
2t invalid name
r(198);

. gen y2 = 1.2w + 6
2w invalid name
r(198);

. gen y3 = 2x + 6
2x invalid name
r(198);


. tab y

          y |      Freq.     Percent        Cum.
------------+-----------------------------------
         72 |         10      100.00      100.00

      Total |         10      100.00
