Add verb is used to add two or more numbers. The result is stored in the destination operand.

Syntax

ADD A B TO C D                                  ---- Syntax 1

ADD B C D  TO  E GIVING F                 ---- Syntax 2

ADD CORR WS-GR1 TO WS-GR2         ---- Syntax 3


In syntax 1, A, B, C  are added and the result is stored in C. i.e C=A+B+C and A, B, D are added and result is stored in D.
i.e D = A+B+D

In syntax 2, B, C, D & E are added and the result is stored in E.
i.e E = B+C+D+E

In syntax 3, sub grouped item in WS-GR1 and WS-GR2 are added and the result is stored WS-GR2.
