{title:Description}

{p 4 4 2}
{cmd:strltrim(}{it:s}{cmd:)}
returns {it:s} with leading blanks removed.

{p 4 4 2}
{cmd:strrtrim(}{it:s}{cmd:)}

{p 4 4 2}
{cmd:strtrim(}{it:s}{cmd:)}

{p 4 4 2}
When {it:s} is not a scalar, these functions return element-by-element
results.


{title:Remarks}

{p 4 4 2}
Stata understands {cmd:strltrim()}, {cmd:strrtrim()}, and {cmd:strtrim()}, as
synonyms for its own {cmd:ltrim()}, {cmd:rtrim()}, and {cmd:trim()} functions,
so you can use the {cmd:str*()} names in both your Stata and Mata code.
