Basic Operations

Assigning values to ABAP variables
Use ‘=’ or MOVE keyword to assign a value to a variable.

DATA: a TYPE i,
      b TYPE i,
      c TYPE i,
      d TYPE i.

a = 10.
b = a.
MOVE 20 TO c.
MOVE c TO d.

WRITE:/ a, b, c, d.

Output

Basic Arithmetic Operations

DATA: a TYPE i,
      b TYPE i,
      c TYPE i,
      d TYPE i.

*Using Mathematical Expressions
a = 10 + 20.
b = 20 - 10.
c = 10 * 2.
d = 100 / 2.

WRITE:/ 'Using Expressions'.
WRITE:/ a, b, c, d.

*Using Keywords
add 10 to a.
subtract 5 from b.
multiply c by 2.
divide d by 2.

WRITE:/ 'Using Keywords'.
WRITE:/ a, b, c, d.

Output

Clear ABAP variables
Use keyword CLEAR to set the variables to default values.

DATA: a TYPE i,
      b TYPE i.

a = 10 + 20.
b = 20 - 10.

WRITE:/ 'Before Clear'.
WRITE:/ a, b.

clear: a, b.

WRITE:/ 'After Clear'.
WRITE:/ a, b.
