Try e.g.:

version 11
clear all
prog eqn2coef, eclass
 version 9.2
 syntax [, Edit(string) to(string) ]
 tempname b V
 mat `b'=e(b)
 mat `V'=e(V)
 loc cmd `e(cmd)'
 loc N `e(N)'
 tempvar touse
 g byte `touse'=e(sample)
 forv i=1/`=colsof(`b')' {
  mata: chColNames("`b'",`i')
  loc r `"`r' `"main:`r1'"'"'
 loc r: subinstr  loc r `"`edit'"' `"`to'"',all
 mat colnames `b' = `r'
 mat rownames `V' = `r'
 mat colnames `V' = `r'
 eret post `b' `V', e(`touse') obs(`N')
 eret local cmd `"`cmd'"'
 void chColNames(string scalar b, real scalar i)
   st_local("r1", r[i,1])
   st_local("r2", r[i,2])
use, clear
g lnbw=ln(bw)
loc x "parity white male"
loc z "edfwhite edmwhite incwhite cigtax88"
qui ivreg2 lnbw `x' (cigspreg=`z')
est sto ivreg2
qui ivpois bw `x', endog(cigspreg) exog(`z')
est sto ivpois
qui gmm (bw-exp({x:cigspreg `x'} + {_cons})), instruments(`x' `z')
eqn2coef, e(x_)
est sto gmm
esttab *, nogaps eq(1) mti
