Tab

Help!!

Do you know the counterpart of tab in sap?? as in tab space.

I have a code like this:

LOOP AT gt_pr INTO wa_pr.

WRITE wa_pr-pstatu.

ENDLOOP.

wa_pr-pstatu has a value of (1pr , 2rq, 3po).

I need to have an output like this 1pr , 2rq, 3po with a condition that the line is indented.

Do you know how to do it???

Help me please....
