Nick spotted two important points which I overlooked:
> scalar `aqq'=at'[1,5]
should be
scalar `aqq'=`at'[1,5]
Also, the if condition has to be added at the end of the program:
replace `lnc' = .... `if'
replace `sl' = .... `if'
replace `sk' = .... `if'
replace `sm' = .... `if'
where ... stands for the very long expressions in Jingjing's code.
Concerning -trace- and -nlsur-: From my (quick) experiments it
appeared that -trace- will only show details of the program if it is
invoked directly (i.e. without -nlsur-). In order to to that, one has
to be careful to use copies of the dependent variables, since the
program will change those variables if running successfully.
