COMPARE Procedure
VAR Statement
Restricts the comparison of the values of variables
to the ones named in the VAR statement.
Syntax
Required Argument
- variable(s)
-
one or more variables
that appear in the BASE= and COMPARE= data sets or only in the BASE=
data set.
Details
-
If you do not use the VAR statement,
then PROC COMPARE compares the values of all matching variables except
the ones that appear in BY and ID statements.
-
If a variable in the VAR statement
does not exist in the COMPARE= data set, then PROC COMPARE writes
a warning message to the SAS log and ignores the variable.
-
If a variable in the VAR statement
does not exist in the BASE= data set, then PROC COMPARE stops processing
and writes an error message to the SAS log.
-
The VAR statement restricts only
the comparison of values of matching variables. PROC COMPARE still
reports on the total number of matching variables and compares their
attributes. However, it produces neither error nor warning messages
about these variables.
