Specifies a condition or set of
conditions that observations in
an input data set must meet in order to be used for filling variable fields.
| Restriction: |
The WHERE statement is valid only when the
DATA= option is used in the PROC FSLETTER statement to identify the data set.
|
| expression |
is any valid WHERE expression that includes one or
more of the variables in the input data set. Refer to the description of the
WHERE statement in
SAS Language Reference: Dictionary for details about the operators and operands that
are valid in WHERE expressions. |
By default, when you use the DATA= option in the PROC FSLETTER statement,
the FSLETTER procedure generates a copy of the document for every observation
in the data set. If you do not need a copy for every observation, you can
use the WHERE statement to generate copies for only observations that meet
a specified condition or list of conditions.
For example, to print form letters for only observations in which the
value of the variable YEAR is less than 5, follow the PROC FSLETTER statement
with this statement:
where year<5;
In this case, the FSLETTER procedure uses only observations that meet
the specified condition. No documents are printed for observations that do
not satisfy the condition.
