CONCATENATE STMT

Question

Hi Guys,
        can any one send me the syntax for the concatenate stmt.
something like:
concatenate lines of itab into itab1-text  seperated by space. Please if posiible copy it from the SAP help and paste it here.
Its urgent please reply as soon as possible.

Answer 1

Hi,
Concatenate var1 var2 into var3 separated by space.
Also go through the below help
CONCATENATE
Basic form
CONCATENATE f1 ... fn INTO g.
Addition: ... SEPARATED BY h
Note
Like all string processsing statements, you can only use character-type operands here.
If the type of an operand is not STRING, the operand is treated like a type C field, regardless of its actual type, even though no actual conversion takes place.
In an ABAP Objects context, a more severe syntax check is performed that in other ABAP areas. See Only character fields allowed in string processing.
Effect
Combines the fields f1 to fn (n >= 2) and places them in g.
Note that trailing spaces in source fields with type C are ignored (since they cannot be distinguished from "padding" characters). In C strings, on the other hand, they are considered. All fields fi (1 <= i <= n) are used in the length STRLEN( fi ).
The return code is set as follows:
SY-SUBRC = 0:
The result fitted into g.
SY-SUBRC = 4:
The result was too long for g and could only be transferred in the defined length of g.
Example
DATA: ONE(10)   VALUE ' John ',
      TWO(3)    VALUE 'F.',
      THREE(10) VALUE ' Kennedy',
      NAME(20),
      FIRST     TYPE STRING.
CONCATENATE ONE TWO THREE INTO NAME.
NAME has the value ' JohnF. Kennedy'.
But:
MOVE ONE TO FIRST.       "FIRST = ' John'
SHIFT FIRST CIRCULAR.    "FIRST = 'John '
CONCATENATE FIRST TWO INTO NAME.
NAME has the value 'John F.'.
Addition
... SEPARATED BY h
Effect
Inserts the separator h between the fields fi.
h is used in its defined length if it is a C string.
Examples
DATA: ONE(10)   VALUE 'John',
      TWO(3)    VALUE 'F.',
      THREE(10) VALUE 'Kennedy',
      NAME(20).
CONCATENATE ONE TWO THREE INTO NAME SEPARATED BY SPACE.
NAME has the value "John F. Kennedy".
DATA SEPARATOR(4) VALUE 'USA'.
CONCATENATE SPACE ONE TWO THREE INTO NAME
            SEPARATED BY SEPARATOR.
NAME has the value "USA JohnUSA F.USA Ke".
The return code SY-SUBRC has the value 4.
Note
Performance:
You should use CONCATENATE instead of writing your own routines, since it is safer, quicker, and easier to understand. The runtime required to concatenate two 30 byte fields is approximately 14 msn (standard microseconds).

Ram
