Daniel Klein gave very good advice.
In addition, I note that this program invokes a local macro -basic- which is never defined.
I guess that you misunderstand local macros. If local macro -basic- is defined somewhere else, that is quite immaterial. -NHreg- can't see it.

I need to define a program that can return the observations that are
used in multivariate probit model. Here is the program I write
capture program drop NHreg
program define NHreg,eclass
mvprobit (T1=`basic') (T2=`basic') (T3=`basic') (T4=`basic'),robust
ereturn scalar O=e(N)
end
Then in stata I run written command
NHreg
Stata return " J(): 3204 matrix found where scalar required
<istmt>: - function returned error
"
Do anyone know what is wrong here?
Thank you!
