If balance < 100 then risk = "high"
,
then add balance
as the condition term and risk
as
the action term.
If balance < 100 then risk = "high"
,
the expression for balance
is <
100

is =
"high"
.

when
you use them with logical operators such as AND or OR.
5+x
for an expression, the expression
resolves to =5+x
.
>5
and <10
for myterm
, the expression
resolves to myterm>5 and myterm<10
. SAS Decision Manager
inserts the term for top-level AND or OR operators in condition expressions
only. It does not insert the term with nested AND or OR operators
or in action expressions.
+1
is
invalid. If you enter +1
as an action expression,
the expression resolves to x=x + 1
. The expression =+1
is
invalid as both a condition and as an action expression.
-1
as
either a condition or an action expression, the expression is interpreted
as a negative number and not as a leading minus operator. The expression
resolves to x=-1
.

x
and term1
are
equal to 5. The recommended way to enter this expression is =5
and term1=5
.
term1
is equal to 5, and
if so, assigns a value of 1 (true) to x
.
If not, it assigns a value of 0 (false) to x
.
x
and term1
are
equal to 3 or whether term2
is equal to 5.
The recommended way to enter this expression is (=5 or
term1=3) or term2=5
.
term1
is equal
to 3 or term2
is equal to 5, and if so, assigns
a value of 1 (true) to x
. If not, it assigns
a value of 0 (false) to x
.
rate
is equal to high

,
and if so, assigns a value of 1 (true) to x
.
If not, it assigns a value of 0 (false) to x
