where {it:numlist} contains {it:{help numlist:numlist_elements}} 
and may contain sequences of missing value codes, such as 
{cmd:.a/.c} and {cmd:.a(3).o}.

{p 10 12 2}
The type of {it:nlist} is irrelevant and it is replaced 
with a {it:real colvector}.


{title:Description}

{pstd}
{cmd:elabel_numlist()} expands a {it:string scalar} that contains a numeric 
list including sequence operators. The function returns the same thing as 
Stata's {helpb nlist:numlist} command but additionally expands sequences 
of (extended) missing value codes, such as {cmd:.a/.c}, treating the 
distance between successive missing value codes as 1. If {it:integer}!=0, 
only integer values are allowed in {it:numlist}; if {it:nosysmiss}!=0, 
system missing values ({cmd:.}) are not allowed in {it:numlist}.

{pstd}
{cmd:_elabel_numlist()} does the same thing but places the expanded numeric 
list as a {it:real colvector} in {it:nlist} and returns the error code.

{title:Diagnostics}

{pstd}
{cmd:elabel_numlist()} exits with Stata return code 121 if 
{it:numlist} is not a valid numlist, with return code 126 if 
{it:numlist} contains noninteger values, and with return code 
127 if {it:numlist} contains system missing values.

{pstd}
{cmd:_elabel_numlist()} places in {it:nlist}, J(0, 1, .) and returns 
the respective error code if {it:numlist} is not a valid numlist.
