Could someone please explain the following behavior?  I'm running fully
up to date Stata 8.2 on Windows 2000.

In a program I have the following statements (with responses
interspersed):

. local x = -4
. display `x'
-4
. local xsq=`x'^2
. disp `xsq'
-16

I kind of expected xsq to have the value of 16 rather than -16.

Thanks in advance.
There is a FAQ on this.  See
