Move & Compute:
MOVE source TO target.
COMPUTE target = source.
DATA : d1(4),
d2 TYPE I VALUE 75,
d3 TYPE I.
MOVE ‘SAP’
TO d1.
COMPUTE d3
= d2 + 125.
If source & target fields have different type
then source is converted in the format of target.

Basic Assignment Operations
Syntax: MOVE
<f1> TO <f2>
The MOVE statement transports the contents of the
source field <f1>, which can be any data object, to the target field
<f2>
The MOVE statement and the assignment operator have
the same function. The above statement when written with assignment operator
(=) has the form:
f2 = f1.
Example:
DATA: T(10),
NUMBER TYPE P DECIMALS 1,
COUNT TYPE P DECIMALS 1.
T =
1111.
MOVE ‘ 5.3 ‘
TO NUMBER.
COUNT =
NUMBER.
The result of this assignment is that fields T,
NUMBER, and COUNT contain the values ‘ 1111 ’, ‘ 5.3 ‘, and ‘ 5.3 ‘.
Assigning values with Offset specifications
You can Specify offsets and lengths for elementary
data objects in every ABAP/4 statement.
Syntax:
MOVE <f1> [+<p1>][(<l1>)] TO
<f2> [+<p2>][(<l2>)].
The contents of the section of field <f1>,
which begins at the position <p1>+1 and has a length of <l1>, are
assigned to field <f2> where they overwrite the section which begins at
the position <p2>+1 and has a length of <l2>.
In the MOVE statement, all offset and length
specifications can be variables.
Example:
DATA:F1(8) VALUE
‘ABCDEFGH’,
F2(8).
DATA:O TYPE I VALUE 2,
L TYPE I VALUE 4.
MOVE F1 TO
F2.
Write / F2.
MOVE F1+O(L) TO
F2.
Write / F2.
MOVE F1 TO F2
+O(L).
Write / F2.
CLEAR F2.
MOVE F1 TO F2
+O(L).
Write / F2.
MOVE
F1+O(L) TO F2+O(L).
Write / F2.
The above example produces the following output:
ABCDEFGH
CDEF
CDABCD
CDEF
Copying values between components of Field Strings
Syntax:
MOVE-CORRESPONDING <STRING1> TO <STRING2>.
This statement assigns the contents of the
components of field string <string1> to those components of field string
<string2> which have the same names.
The system executes a MOVE statement for each name
pair as follows:
MOVE STRING1- <component> TO STRING2-
<component>
