I could also see Adriaan extending the -syntax- line to include an option to
indicate which statistics the user wants. Having Stata query the user during
the execution of a -program- is quite unusual - though Adriaan specifically
asked for that...

Wow!
Thank you, Martin (and Michael) for your reactions to my post.
Very helpfull...

Try:

*******

cap pr drop my_summarize

prog my_summarize
        vers 11.0
        syntax varname
        di in r "Type 1 if you want mean and standard deviation" _n /*
        */ "Type 2 if you want median an interquartile range"  /*
        */ _request(myrequest)
        qui{
         su `varlist', det
        if $myrequest==1 {
                noi di _n(2) in r "mean: " r(mean) ", sd: " r(sd)
        }
        else if $myrequest==2 {
                noi di _n(2) in r "median: " r(p50) ", iqr: "
`=r(p75)-r(p25)'
        }
        else{
                noi di _n(2) in r "I said 1 or 2..."
        }
}
end
*******


Then say:


*******
sysuse auto, clear
my_summarize mpg
//upon request:
1
my_summarize mpg
//upon request:
2
my_summarize mpg
//upon request:
3
*******

Have you had a look at

*******
h display
*******

and the -_request- syntax?

Hoogendoorn, Adriaan

Is it possible to write a procedure that interacts with the user?
To give an example of what I mean, suppose that I could create such an
interacting procedure "my_summarize" (in a do file) ending with:

sysuse auto
my_summarize mpg

Now  I would like Stata to interact with the user, and want Stata to
come up with the following suggestion:
Type 1 if you want mean and standard deviation or
Type 2 if you want median an interquartile range.
Please type either 1 or 2.
.
Typing 1 or 2 from would now result in either the mean and sd of mpg or
its median and iqr.

Is such an approach (or some alternative) possible in Stata?
