{title:Reverse Variable Value Order}

{p 8 14 2} {cmd:revrs} [{it:varlist}] [{cmd:,} {cmdab:repl:ace}]

{title:Description}

{p 4 8 2}{cmd:revrs} reverses the value {bf:order} of the specified variables and maintains the appropriate value labels. 
Without the {cmd:replace} option specified, the command will create a new variable called {it:rev`origvar'}. This command is 
especially useful for keeping variables with categorical response options all ordered in the same manner (e.g., "Most Important" always is highest value).

{p 4 8 2}{err:WARNING:} This command only applies to the order of the values of the variable NOT the values themselves. The new reversed
version of the variable will {bf:always} start at 1.

{title:Options}

 
{p 4 8 2}{cmd:replace} replaces the original variable with the reversed version. If invoked, it is applied to all variables in {it:varlist}.
