{p 5}
{cmd:labmm} {hline 2} Modify multiple value labels


{title:Syntax}

{p 8}
{cmd:labmm} [{it:lblname-list}] {it:#} {cmd:"}{it:label}{cmd:"} 
[{it:#} {cmd:"}{it:label}{cmd:"} {it:...}]


{title:Description}

{pstd}
{cmd:labmm} modifies (multiple) value labels. All value labels 
specified in {it:lblname-list} are modified according to definitions. 
If {it:lblname-list} is not specified it defaults to {hi:_all}, 
meaning all value labels in memory. Note that value labels must 
exist.

{pstd}
{hi:Reminder:} modifiactions affect all variables that have the same 
value label as one of the value labels (or variables - see 
{help labmm##r:Remarks}) in {it:lblname-list} attached.

{pstd}
Also this is no longer shown in the syntax diagram, {it:lblname-list} 
is actually {it:namelist} and allows variable names. Thus, the syntax 
diagram reads

{p 8}
{cmd:labmm} [{it:lblname-list}|{varlist}] 
{it:#} {cmd:"}{it:label}{cmd:"} 
[{it:#} {cmd:"}{it:label}{cmd:"} {it:...}]

{pstd}
The reason this is no longer shown, is that specifying variable names 
to refer to value label names violates Stata conventions. If variable 
{hi:foo} has value label {hi:foobar} attached, specifying {hi:foo} in 
{it:varlist}, modifies value label {hi:foobar}. The modifications also 
affect variable {hi:bar}, if {hi:bar} has value label {hi:foobar} 
attached. I thank Daniel Possenriede for bringing this to may 
attention again.

{title:Acknowledgments}

{pstd}
Modifying multiple value labels was suggested by Anna Reimondos on 
{browse "http://www.stata.com/statalist/archive/2010-04/msg00554.html":Statalist}.
Michael Norman Mitchell's solution led to this ado.
