{p 5}
{cmd:lab2varn} {hline 2} Rename variables to match variable labels


{title:Syntax}

{p 8}
{cmd:lab2varn} {varlist} 
[{cmd:,} {opt d:ryrun} {opt t:runcate(#)}]


{title:Description}

{pstd}
{cmd:lab2varn} changes names of variables to respective variable 
labels. In variable labels, (consecutive) invalid characters are 
changed to one underscore ({hi:_}). Trailing blanks are stripped, 
while leading blanks are changed to underscore.


{title:Options}

{phang}
{opt dryrun} does not rename variables, but produces a report.

{phang}
{opt truncate(#)} truncates variable labels after {it:#} characters. 
Default {it:#} is 32.


{title:Remarks}

{pstd}
The program is best used in combination with 
{stata findit labvarch:labvarch} (Nick Cox).


{title:Examples}

{phang2}{cmd:. sysuse auto}{p_end}
{phang2}{cmd:. lab2varn foreign}{p_end}


{title:Saved results}

{pstd}
{cmd:lab2varn} saves the following in {cmd:r()}:

Macros{p_end}
{synoptset 15 tabbed}{...}
{synopt:{cmd:r(oldnames)}}old variable names{p_end}
{synopt:{cmd:r(newnames)}}new variable names{p_end}


{title:Acknowledgments}

{pstd}
A question from Mark Kaulisch inspired this ado.

{pstd}
Part of the code is borrowed from {stata findit dummieslab:dummieslab} 
by Nick Cox and Philippe van Kerm.
