HI

<b>STRING_REVERSE</b> Returns a string in reverse order

<b>Functionality</b>

The function module returns the character string entered in reverse sequence. Leading blanks are taken into account, trailing blanks are not.

All exceptions are generated with RAISE and must be handled in the calling program.

<b>Examples</b>

' abc ' becomes 'cba ' . (If the actual parameter assigned to the formal parameter RSTRING is longer than 4 characters as shown in this example, the remaining places are padded with blanks.)

Sample call:

DATA: REVERSESTRING(10).

CALL FUNCTION 'STRING_REVERSE'

EXPORTING STRING = ' abcdef '

IMPORTING RSTRING = REVERSESTRING

EXCEPTIONS TOO_SMALL = 1.

IF SY-SUBRC = 0.

• The reverse string is in RSTRING

ELSE.

• RSTRING zu kurz

ENDIF.

<b>Reward if usefull</b>

hi Khanna,

by import parameter LANG you have to give the language to the system. This should be system wise, so you have to take care about conversions.
