MOVE
Variants
1. MOVE f TO g.
2. MOVE f+off1(len1) TO g+off2(len2).
3. MOVE c1 TO c2 PERCENTAGE n.
Variant 1
MOVE f TO g.
Effect
Moves the contents of field f to field g .
Field f remains unchanged.
This statement is equivalent to:
-
g = f.
Example
-
DATA: NUMBER TYPE I,
FIVE TYPE I.
MOVE 5 TO FIVE.
MOVE FIVE TO NUMBER.
The fields NUMBER and FIVE now both 5.
Notes
Multiple assignments like
NUMBER = FIVE = 5.
are also possible. ABAP/4 executes them from right to left (as in the
above example).
If the field types or lengths differ, type conversion follows
automatically. Type I fields are handled like type P fields. If
you select the fixed point arithmetic attribute for an ABAP/4
program, type P fields are either rounded according to the number of
decimal places or filled with zeros.
In contrast to WRITE TO , the
decimal character is always a period (.), regardless of the
specification in the user master.
MOVE allows you to copy tables and structures which contain
other tables.
Two tables can be copied only if this is possible for their respective
lines. If the line types are incompatible, conversions are performed
line by line. If itab is a table with a header line, the table
itself can be addressed with itab[] .
Two structures which themselves contain tables can only be copied if
they are compatible (i.e. if the ABAP/4 type check allows this).
Conversion table ( f -> g ) depending on the types of
f and g :
C -> C Left-justified transfer. If the target field is longer than the
source field, it is padded with blanks on the right. If it is shorter
than the source field, the left part of the source field is copied and
the rest is truncated.
C -> D The field f must be an 8-character date in
YYYYMMDD format.
C -> F The character string in f must be a valid representation
of a floating point number (DATA ).
C -> N Only the digits in f are valid here. They are moved to
g , right-justified and padded with zeros on the left. If the
target field is too short, digits on the left are truncated.
C -> T The field f must contain a 6-character time
specification in HHMMSS format.
C -> P the field f must contain a decimal number, i.e. a
sequence of numeric characters with optional signs and more than once
decimal point; there may be blanks on either side. If g is too
short, an overflow error can occur.
C -> X The field f must contain a hexadecimal character string
(i.e. the only valid characters are 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F).
The number to be converted is treated as a hexadecimal number rather
than a decimal number,
e.g.: C'15' -> X'15' .
It is transported left-justified to g and either padded with
zeros or truncated,
e.g.: C'AB' -> X'AB00' .
f is processed up to the first blank.
Examples:
C'ABC' -> X'ABC0', C'ABC0' -> X'ABC0'
C'ABC D' -> X'ABC0', C' AB' -> X'0000'
D -> C Left-justified transfer without conversion
D -> D Transfer without conversion
D -> F As for D -> P and then P -> F
D -> N As for D -> C and then C -> N
D -> P Inverse of P -> D
D -> T Not supported: Error message
D -> X Inverse of X -> D
F -> C f is converted to E format and moved
to g . E.g.: F'-3.142' -> C'-3.14200000000000E+00'
If the mantissa is unequal to 0, it is standardized so that it lies
between 1.0 and 9.99...
The exponent is generally 2-digit; it is only converted to 3-digit
format if it is greater than 99 or smaller than -99
The exponent always appears with a sign.
If g is too short, the mantissa is rounded.
e.g.: F'3.152' -> C' 3.2E+00' .
The length of g should be at least 6, otherwise it g is
filled with asterisks (*).
F -> D See F -> N
F -> F Transfer without conversion
F -> N f is rounded as with F -> P and then treated like a P
field.
F -> P f is rounded, e.g. F'-3.512' -> P'-4' .
F -> T See F -> N
F -> X See F -> N
N -> C f is treated like a C field; leading zeros remain.
N -> D As for N -> C and then C -> D
N -> F As for N -> P and then P -> F
N -> N Right-justified transfer; on the left, padded with zeros or
truncated.
N -> P f is packed and moved to g with a positive sign
(+). If g is too short, an overflow error can occur.
N -> T As for N -> C and then C -> T
N -> X As for N -> P and then P -> X
P -> C f is moved to g with a trailing sign and, if
required, a decimal point.
e.g.: P'-1234567' -> C'12345.67-'
Notes:
1) One position is always reserved for the sign and, in the event of a
positive number, a blank is output.
2) Leading zeros are output as blanks.
3) If g is too short, the blank representing the sign in the
case of positive numbers is omitted; if this is insufficient, the
number is truncated on the left - this is indicated by an asterisk (*).
Examples (the P field f has the length 2, the C field g
the length 3):
P'123' -> C'123', P'-123' -> C'*3-'
4) If you do not want to reserve a position for the sign, use the
WRITE TO statement with the addition
NO-SIGN .
5) To convert with leading zeros and without formatting characters, use
the UNPACK statement.
P -> D The value in f is the absolute date (i.e. the number of
days since 01.01.0001) and is moved to g in the YYYYMMDD
format. This takes into account that the Julian Calendar was replaced
by the Gregorian Calendar on 15.10.1582. The value 0 (and negative
values) are transferred into the initial date '00000000'.
P -> F The field f is moved to g as a floating point
number.
P -> N Right-justified transfer without sign; padded with zeros on the
left.
P -> P If g is too short, an overflow error can occur.
P -> T The value in f is an absolute time (i.e. the number of
seconds since midnight modulo 24 hours = 86.400 seconds) and is moved
to g in HHMMSS format.
P -> X The value in f is stored in g as a hexadecimal
number. E.g.: P'15' -> X'0F' .
Negative numbers are represented by the two's complement.
e.g.: P'-153' -> X'FF67' .
If the length of g is greater than 4, only the last 4 Bytes are
provided for according to the value of f ; the Bytes before them
are padded with Hex-0.
If g is too short, the number is truncated on the left.
T -> C As for D -> C
T -> D Not supported: Error message
T -> F As for T -> P and then P -> F
T -> N As for T -> C
T -> P Inverse of P -> T
T -> T Transfer without conversion
T -> X Inverse of X -> T
X -> C f is converted to hexadecimal format. The result is
transferred left-justified and padded with blanks or truncated on the
right.
e.g.: X'0F' -> C'0F'
X -> D The value in f is an absolute date (number of days since
01.01.0001) and is moved to g in YYYYMMDD format. (See
also P -> D.)
X -> F As for X -> P and then P -> F
X -> N As for X -> P and then P -> N
X -> P f is treated as a hexadecimal number and moved to
g in decimal packed format.
e.g.: X'0F' -> P'15'
If f is longer than 4, only the last 4 bytes are processed.
If g is too short, an overflow error can occur.
X -> T The value in f is an absolute time (i.e. the number of
seconds since midnight modulo 24 hours = 86,400 seconds) and is moved
to g in HHMMSS format. (See also P -> T.)
X -> X Left-justified transfer; padded with X'00' on the right
or truncated.

Variant 2
MOVE f+off1(len1) TO g+off2(len2).
Effect
With offset off2 and length len2 , field
g receives the contents of field f with offset
off1 and length len1 .
Therefore, the offset and length specifications can also be variable.
Example
-
DATA: FIELD1(10) VALUE '1234567890',
OFF1 TYPE I VALUE 1,
LEN1 TYPE I VALUE 2,
FIELD2(8) VALUE 'abcdefgh',
OFF2 TYPE I VALUE 3,
LEN2 TYPE I VALUE 4.
MOVE FIELD1+OFF1(LEN1) TO FIELD2+OFF2(LEN2).
FIELD2 now has the value ' abc23 h '.
Variant 3
MOVE c1 TO c2 PERCENTAGE n.
Additions
1. ... LEFT
2. ... RIGHT
Effect
c1 and c2 must be type C fields; n
is a field with a numeric value between 0 and 100. The left part of
field c1 ( n percent) is moved to field c2 and is
left-justified. c2 is filled with blanks if necessary.
Addition 1
... LEFT
Effect
This is the standard. With this statement, you can make
clear that transfer is to be left-justified.
Addition 2
... RIGHT
Effect
Transfer is right-justified, the left part of field
c1 as standard.
Note
Performance
The runtime required to transfer a C(1) field to a C(1) field is 1
msn (standard microseconds).
Conversions should be avoided for performance reasons, i.e. the fields
should have the same type and length. For example, a MOVE of
a C(10) field to a C(10) field takes about 2 msn, while a
MOVE of a C(10) field to a type I field needs about 10 msn.
