Hi,

I would like to create some ado-files in order to replicate some estimations on several data.
I have some problems calling ml program in my ado (they are not known).

Let's take a small example : 

/*----------------------------- begin Example.ado-----------------------------*/
program Example
    version 11.1
    args varY X1 X2
    use http://www.stata-press.com/data/r11/auto
    
    di "Call myprobit"
    ml model lf myprobit (`varY' = `X1'  `X2')
    ml maximize
end

program myprobit
    version 11
    args lnf theta1
    quietly replace `lnf' = ln(normal(`theta1')) if $ML_y1==1
    quietly replace `lnf' = ln(normal(-`theta1')) if $ML_y1==0
end
/*----------------------------- end Example.ado-----------------------------*/

Running the ado "Example" gives the following message : 


. Example foreign mpg weight
(1978 Automobile Data)
Call myprobit
unrecognized command:   myprobit
r(199);"

I don't understand why the program "myprobit", written in the ado file, remains unknown...
What is my mistake???
Thanks a lot.

valérie
