Sergiy--
Error codes above 9999 are probably safe, though Stata can reclaim or
reassign error codes as they see fit--e.g. errors 3000-3999 pre- and
post-Mata.  Note also that
 version 5: error 3001
does not recover old error codes!  It's safer to use an error code
that Stata already assigns a message to, preferably one that seems
unlikely to be reassigned (198 is safest).

One can construct one's own list of predefined informative error codes
for the current version like so:

clear all
prog errors
tempfile e l
tempname t
file open `t' using `e', write replace
forv i=1/9999 {
 file write `t' _n "error `i'"
 }
file write `t' _n
file close `t'
cap log close
cap log using `l', text
do `e', nostop
cap log close
insheet using `l'
end
errors
g err=real(substr(v1,9,.))
g msg=v1[_n+1]
drop if mi(err)
drop if mi(msg)
drop if substr(msg,1,2)=="r("
drop if msg=="Mata run-time error"
brow err msg
