DATA lv_char2 TYPE string VALUE 'World'.
DATA LV_CHAR3 TYPE C LENGTH 50.
DATA(lv_string3) = |{ lv_char1 } { lv_char2 }!|.
WRITE: / lv_string3.
DATA(lv_string2) = lv_char1 && | { lv_char3 } | && lv_char2 && '!' .
WRITE: / lv_string2.
CONCATENATE lv_char1 lv_char3 lv_char2 '!' INTO DATA(lv_string4) RESPECTING BLANKS.
WRITE: / lv_string4.

DATA: lv_search TYPE String VALUE 'hello world',
lv_palceholder TYPE String.
DATA lv_length TYPE I.
lv_length = strlen( lv_search ).
do lv_length times.
