What is ment by following statements?
ASSIGN A INCREMENT B TO <FS>.
ASSIGN A INCREMENT <FS1> TO <FS2>.
ASSIGN <FS1> INCREMENT <FS2> TO <FS3>.

Hi,
Increments the field symbol <fs>, starting from f, by n times the length of f. You cannot use offset/length addressing in f. If the system cannot assign f to the field symbol - that is, if it addresses an invalid memory area - the field symbol remains unchanged and sy-subrc is set to 4.
SY-SUBRC = 0:
The field was assigned successfully.
SY-SUBRC = 4:
The field was not assigned successfully. the field symbol
remains unchanged
Example
DATA: cf(26) TYPE c VALUE 'abcdefghijklmnopqrstuvwxyz'.
FIELD-SYMBOLS: <fs> TYPE c.
ASSIGN cf(2) TO <fs>.
DO 5 TIMES.
WRITE <fs>.
ASSIGN <fs> INCREMENT 3 TO <fs>.
ENDDO.
In this example, the field symbol points to the first two characters of the field cf. Then in each loop pass, the field symbol is incremented 3 times 2 characters. The system then displays the result: ab gh mn st yz.
Example
TYPES: BEGIN OF comp,
f1 TYPE string,
f2 TYPE i,
END OF comp.
DATA: BEGIN OF stru,
k1 TYPE comp,
k2 TYPE comp,
k3 TYPE comp,
k4 TYPE comp,
END OF stru.
FIELD-SYMBOLS: TYPE comp.
ASSIGN stru-k1 TO RANGE stru.
DO 4 TIMES.
...
ASSIGN INCREMENT 1 TO .
ENDDO.
This example shows you how to edit a sequence of identically-typed sub-structures in a loop.
