CONCATENATE

Basic form

CONCATENATE f1 ... fn INTO g.

Addition

... SEPARATED BY h

Effect

Places the fields f1 to fn after g .

With the fields fi (1 <= i <= n), trailing blanks are ignored, i.e. these fields are considered only to have the length STRLEN ( fi ).

The return code value is set as follows:

SY-SUBRC = 0 The result fits in g .
SY_SUBRC = 4 The result was too long for g and was only copied to g in that length.

Example


DATA: ONE(10)   VALUE 'John',
      TWO(3)    VALUE ' F.',
      THREE(10) VALUE ' Kennedy',
      NAME(20).
CONCATENATE ONE TWO THREE INTO NAME.

Then, NAME contains the value " John F. Kennedy ".

Addition

... SEPARATED BY h

Effect

Inserts the separator h between the fields fi .
Here, h is used in its defined length.

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.

Then, NAME has the value " John F. Kennedy ".


DATA SEPARATOR(4) VALUE 'USA'.
CONCATENATE SPACE ONE TWO THREE INTO NAME
            SEPARATED BY SEPARATOR.

Then, NAME has the value " USA JohnUSA F.USA Ke ".
The return value of SY-SUBRC is set to 4.

Note

Performance

You are recommended to use the key word CONCATENATE rather than your own constructions because it is safer, more efficient and clearer. The runtime required to append two 30-byte fields amounts to approx. 14 msn (standardized microseconds).
