REPLACE


Basic form

REPLACE f WITH g INTO h.

Addition



... LENGTH len (length specification for field f )

Effect

Replaces the first occurrence of the contents of field f in field h with the contents of field g . All fields are handled in their defined length; this means that closing blanks are not ignored.

The return code value indicates whether the string f was found in h and replaced by g :

SY-SUBRC = 0 String replaced.
SY_SUBRC = 4 String not replaced.

Example

DATA FIELD(10). MOVE 'ABCB' TO FIELD. REPLACE 'B' WITH 'string' INTO FIELD.

returns:

FIELD = 'AstringCB', SY-SUBRC = 0

Note

The fields f and g in the REPLACE statement should not overlap. Otherwise, the result is undefined.

Addition

... LENGTH len ... (length specification for field f )

Effect

Searches for the string f in the field h not in its (full) field length, but in the length len .

Example

DATA: PATTERN(5) VALUE 'ABC', LEN TYPE I, REPL_STRING(5) VALUE '12345', FIELD(12) VALUE 'abcdeABCDE'. REPLACE PATTERN WITH REPL_STRING INTO FIELD.
does not change FIELD , since 'ABC ' does not occur in abcdeABCDE ' .
LEN = STRLEN( PATTERN ). REPLACE PATTERN LENGTH LEN WITH REPL_STRING INTO FIELD.
changes FIELD to 'abcde12345DE' .
