{title:Description}

{pstd}
{cmd:set} {cmd:varabbrev} allows you to control whether variable abbreviations
are allowed.  The default is to allow variable abbreviations.


{title:Remarks}

{pstd}
If you type

	{cmd:. sysuse auto}
	{cmd:. summarize mp}

{pstd}
you will see a summary of the variable {cmd:mpg} since {cmd:mp} is
an abbreviation of {cmd:mpg} and no other variable in the dataset
can be abbreviated to {cmd:mp}.

{pstd}
If you turn off variable abbreviations with

	{cmd:. set varabbrev off}

{pstd}
Stata will not find the variable {cmd:mpg} when you type {cmd:mp} in
a variable list.
