Subject   st: last estimation results not found, nothing to store -- Error message

Hi All,

Stata issues an error message saying "last estimation results not
found, nothing to store" when I try to store estimation results from
an estimation command I wrote. However, when I type -ereturn list-,
all the saved scalars, matrices, macros and so on show up. Stephens
Jenkins experienced a similar problem back in 2008, maybe becasue he
did not generate his results within an -eclass- program (check out:
http://www.stata.com/statalist/archive/2008-06/msg00196.html).

But in my case, I follow religiously the basic outline suggested by
StataCorp and I still get the error message (see program code below).
Does anyone know what might trigger this error and how to fix it?

Thanks

Here is the structure I used for the estimation command:

********** Code begins***********************
program myest, eclass
version 11
if !replay() {
syntax whatever [, whatever Level(cilevel)]
marksample touse // see [P] mark

* Here I perform any other parsing of the user’s estimation request;

local depn "dependent variable name"
local nobs = number of observations in estimation
tempname b V

* Here I produce coefficient vector `b' and variance–covariance matrix `V'

ereturn post `b' `V', obs(`nobs') depname(`depn') esample(`touse')
ereturn local depvar "`depn'"

* Here I store stuff I want in e()

ereturn local cmd "myest" // set e(cmd) last
}
else { // replay
if "`e(cmd)'"!="myest" error 301
syntax [, Level(cilevel)]
}

* Here I output header above the coefficient table;

ereturn display, level(`level')

*Here I perform some housekeeping

end
