st: problem scatterplot in Stata11

[Peter Claeys <peter.claeys@ub.edu>]

Hi,

I run the following command in Stata11 to produce a scatterplot of two 
series, X and Y
twoway (scatter X Y, mlabel(country)) (lfit X Y)

and get the following error message:

option mtextq() not allowed
r(198);

As far as I can see from the Help function on twoway scatter plots, 
there is nothing wrong with the syntax of the command, nor with the 
syntax of the options. What is missing: the version of Stata? the right 
do file, ...?
thanks,

Peter
