Enter the name of the
variable at the prompt. If it is a character variable, then select
the
Character data check box and, if you
want, enter a value in the
Length field.
The length can be any integer between 1 and 200. If you leave the
field blank, then PROC REPORT assigns a length of 8 to the variable.
After you enter the
name of the variable, select
Edit Program to open the
COMPUTE window. Use programming
statements in the
COMPUTE window to define
the computed variable. After closing the
COMPUTE and
COMPUTED VAR windows, open the
DEFINITION window to describe how to display the computed
variable.
Note: The position of a computed
variable is important. PROC REPORT assigns values to the columns in
a row of a report from left to right. Consequently, you cannot base
the calculation of a computed variable on any variable that appears
to its right in the report.
