13 do 5 times.
14 it-f1 = sy-index * 10.
15 it-f3 = 'XX'.
16 it-f2 = it-f4 = sy-index.
17 read table it
18 with key f1 = it-f1
19 binary search

21 if sy-subrc <> 0.
22 insert it index sy-tabix.

26 loop at it.
27 write: / it-f1, it-f2, it-f3, it-f4.
28 endloop.
in this program changing value of sy-tabix as such sy-index.
means in it's first loop it's value is 1, on second loop it's 2, and so on up to 5.
okay that is due to binary search.
but why binary search affecting this system variable?
