+ Unary positive operator

+ Unary positive operator

Preserves the positive or negative value of a numeric expression. Do not confuse this operator with the addition operator that you use to add expressions together.

Syntax
+ expression 
expression

An expression whose value is numeric.

Example

In the r-unpos.p example, the sign of CreditLimit is preserved as is the sign of the sum of CreditLimit + 100. The unary positive is not necessary; it is used simply to document the procedure, as shown:
r-unpos.p
DEFINE VARIABLE old-max NO-UNDO LIKE CreditLimit LABEL "Old Limit". 
FOR EACH Customer: 
  old-max =+ Customer.CreditLimit. 
  Customer.CreditLimit =+ (Customer.CreditLimit + 100). 
  DISPLAY Customer.Name old-max Customer.CreditLimit. 
END.
