+ 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.
