Comparing observations within a data file
-----------------------------------------

         ^compobs^ varlist ^if^ ^_n==#^ [^,^ ^l^ist^(^varlist^)^ ^n^umber^(^#^)^ ]


Description
-----------

^compobs^ compares two observations in the same data file.  By default, ^compobs^
compares two adjacent observations.  The ^if^ clause is required and identifies
the second of the two observations.  ^compobs^ displays the values of each
variable that differs across observations and the number of differences found.


Options
-------

^list(^varlist^)^ specifies one or more variables to be displayed with each
	difference.

^number(^#^)^ specifies the observation to use for comparison when the observations
	are not adjacent.
