String Operations

CONCATENATE – Combines 2 or more strings into one string.

DATA: s1(10) VALUE 'Hello',
      s2(10) VALUE 'ABAP',
      s3(10) VALUE 'World',
      result1(30),
      result2(30).

CONCATENATE s1 s2 s3 INTO result1.
CONCATENATE s1 s2 s3 INTO result2 SEPARATED BY '-'.

WRITE / result1.
WRITE / result2.

Output
String-Operations-1

If the the concatenated string fits in the result string, then the system variable sy-subrc is set to 0. If the result has to be truncated then sy-subrc is set to 4.

SPLIT – Splits a string into 2 or more smaller strings.

DATA: s1(10), s2(10), s3(10),
      source(20) VALUE 'abc-def-ghi'.

SPLIT source AT '-' INTO s1 s2 s3.

WRITE:/ 'S1 - ', s1.
WRITE:/ 'S2 - ', s2.
WRITE:/ 'S3 - ', s3.

Output
String-Operations-2

DATA: string(30) VALUE 'SAP ABAP Development',
      str(10) VALUE 'ABAP'.

IF sy-subrc = 0.
  WRITE:/ 'Found'.
ELSE.
  WRITE:/ 'Not found'.
ENDIF.
