I know, I know, it was not the "first shot" that I thought it would be. The
server sometimes delivers messages in a weird order. I got Kit Baum`s reply
after sending my own message... Sorry for the fuss.

Subject: st: RE: Problem with outreg2 in a do file
Let me take a first shot at this and say that results are usually returned
as -return scalar- by a program. I bet your problem has something to do with
the use of locals inside your program, and different handling of those in a
do-file vs. interactive use. See -h simulate- at the bottom for an example
of the -return scalar- command. Other listers will probably elaborate on
this.
HTH,
Martin

Subject: st: Problem with outreg2 in a do file
Hello,
I have a problem with a certain -outreg2- line that does not work in a
do-file, but works perfectly when called up manually. I really can't
understand why that happens.
Here's the program. What I am doing there is defining a program to
test a nonlinear combination of coefficients (the long-run effect in a
dynamic panel), and therefore I create "testlreff". There, I save the
results (which are matrices) in scalars, so that I can use them in
-outreg2, addstat()-.
*** code begins here***
cap program drop testlreff
program testlreff
nlcom _b[L1.x]/(1-_b[L1.y])
mat b1=r(b)
mat v1=r(V)
local b=b1[1,1]
local se=sqrt(v1[1,1])
end
xtabond2 y L.(y x) yr* , gmm(L.(y)) iv(yr*) iv(L2.x, passthru) noleveleq
robust
testlreff
outreg2 L1.y L1.x using whatever, bdec(3) br addstat(long-run effect,
`b', se, `se') replace
*** code ends here***
The problem that appears when I run this do file is that right after
the outreg-line Stata stops and tells me:
. outreg2 L1.y L1.x using whatever.xls, bdec(3) br addstat(lon
> g-run effect, `b', se, `se')
invalid syntax
r(198);
end of do-file
r(198);
Now the weird thing is that if I now copy and paste that outreg2 line
manually into stata, right after the do file stalls, it works
perfectly. So I really can't understand why it does not work when it
is in a do file.
Thanks for any suggestions!
Davide
