How to find out the index in string.

Question

Hello Experts,
I have a requirement in which i have to find out the index of the last space before the 50th position in a string.
is there any way other than spliting the string.
e.g. if string is - 'aaaa aaaa aaa........ aaa aaa'(length is more than 50)
i want the last space before 50th char.because i want to split the string before last word withing 50 th character
please help.

Hi Shweta,
You can build up the logic from this below program.
data: line(75) value 'abcdefghijk lmnopqrstuvwxyz zyxwvutsrqponml kjihgfedc ba',
       n_line(50),
       off type i,
       val1(50),
       val2(50).
CALL FUNCTION 'STRING_REVERSE'
  EXPORTING
    STRING          = line(50)
    LANG            = ' '
IMPORTING
   RSTRING         = n_line
EXCEPTIONS
   TOO_SMALL       = 1
   OTHERS          = 2.
IF SY-SUBRC NE 0.
   MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
           WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
SPLIT n_line at space into val1 val2.
off = strlen( val1 ).
off = 50 - off.
write: 'The index of the last space before the 50th position is at ', off.
Hope this may help you.
