st: Query re -sortpreserve-

[Roger Newson <roger.newson@kcl.ac.uk>]

Hello All

I am trying to use -sortpreserve- in Stata 7 and Stata 8 under Windows 
98/SE. However, there is one problem. My -sortpreserve- programs do not 
seem to be generating a -`sortindex'- temporary variable, as -[P] 
sortpreserve- says they should. (A simple example under Stata 8 is given 
below.) Why should this be the case?

Best wishes (and thanks in advance)

Roger

r(100);
