{cmd:clonevar}
{newvar} 
{cmd:=}

{ifin}


{title:Description}

{pstd}
{cmd:clonevar} generates {newvar} as an exact copy of an existing variable,
{varname}, with the same {help data types:storage type}, values, and 
{help format:display format} as {it:varname}.
{it:varname}'s {help label:variable label}, {help label:value labels},
{help notes}, and {help char:characteristics} will also be copied.


{title:Remarks}

{pstd}
{cmd:clonevar} has various possible uses.  Programmers may desire that a
temporary variable appear to the user exactly like an existing variable.
Interactively, you might want a slightly modified copy of an original
variable, so the natural starting point is a clone of the original.
