A question about how to use correctly CL_ABAP_CHAR_UTILITIES=>CR_LF

Dear all,

I have a question about inserting new line character in strings.

After googling for a while and also a search among the threads already

in this forum, it seems that CL_ABAP_CHAR_UTILITIES=>CR_LF may be

used in order to insert new line character within a given string content.

Here is what I want to have

DATA text_buffer(500) TYPE c
.
.
.
CLEAR text_buffer.
CONCATENATE
        'line1'
        CL_ABAP_CHAR_UTILITIES=>CR_LF
        'line2'
        CL_ABAP_CHAR_UTILITIES=>CR_LF
        'line3'
        CL_ABAP_CHAR_UTILITIES=>CR_LF
INTO text_buffer.

WRITE text_buffer.

What I expect to have as printed result is

line1
line2
line3

yet what I obtain is this

line1##line2##line3

Any idea? why there is no new line?

Thanks in advance,

Kind Regards,

Dariyoosh
