Dear Friends,

Sorry about the long delay in my answer but I had an emergency in the last few days.

Martin,
I forgot about the “collapse” but I was able to handle it and solve my problem.

Also, the “postfile” suggestion came to be very useful for handling other complication.

Thanks once again for your great help.

How does this example address the -over()- option which Rafael wanted in
addition to conditioning on "mm"?

Note you create a -tempfile- but end up using a permanent one by the name of
"temp1.dta" while `temp1' remains "idle"...

Conditioning on the return code from -summ- is unusual, what is your
intention there? Note that the return code is zero, even if the -if-
qualifier cannot be satisfied:

***
clear*
set obs 1
gen x=5
gen y=7
su x if y==6
di in r _rc
***

You can of course -count- beforehand, and then condition on the returned
value -r(N)- being different from zero...

Does this example help at all?

clear
set obs 100
g var1 = uniform()
g var2 = _n

tempfile temp1

postfile means num mean using "temp1", replace

forval i = 5(5)100 {
capture su var1 if var2  Dear Listers,
