st: Using _diparm

Dear statalist users,

I want to use -_diparm- in the context of an estimation using -ml-.
Having defined a program 'myll' that calculates my maximum likelihood
values, my do-file reads:

ml model lf myll (b: y_observ = x) /logse;
_diparm /logse, exp prob;
ml maximize;

However -_diparm- is answered with an error message, saying  'equation
[/logse] not found'.
I tried to specify -logse:_cons- instead of -/logse- but it was the same.

I wonder whether it is possible to use -_diparm- in a do-file as I did,
because it is a programmer's command.
Can anybody give me a hint about the right syntax and about where to place
the command?
Thanks a lot!
Thomas
