Code Modification

Question

Can i avoid the Case .. Endcase in the following code: (like in C i cud have used array and did something like wa[tabix] = wa_in)
DATA: itab TYPE TABLE OF string,
      sep(3)   VALUE '[*]',
      p_head type string.
data: begin of itab_show Occurs 0,
col1(20),
col2(20),
col8(20),
end of itab_show.
p_head = 'Bolier No.[*]1[*]2[*]3[*]4[*]5[*]6[*]TOTAL'.
  SPLIT p_head AT sep INTO:
                            TABLE itab.
loop at itab into wa_in.
case tabix.
when 1.
wa-col1 = wa_in.
when 2.
wa-col2 = wa_in.
when 8.
wa-col8 = wa_in.
endloop.
Append wa to itab_show.
*... exporting itab_show to smartform interface

Go through the following Link
This documentation should answer your question. I use field symbols when using dynamic programming.
Just go through these links.

Field-Symbols are place holders for existing fields.
A Field-Symbol does not physically reserve space for a field but points to a field, which is not known until run time of the program.
Field-Symbols are like Pointers in Programming language ‘ C ‘.
Syntax check is not effective.
Syntax :
Data : v1(4) value ‘abcd’.
Field-symbols <fs>.
Assign v1 to <fs>.
Write:/ <fs>.
DATA: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA ITAB LIKE SORTED TABLE OF LINE WITH UNIQUE KEY COL1.
FIELD-SYMBOLS <FS> LIKE LINE OF ITAB.
DO 4 TIMES.
LINE-COL1 = SY-INDEX.
LINE-COL2 = SY-INDEX ** 2.
APPEND LINE TO ITAB.
ENDDO.
READ TABLE ITAB WITH TABLE KEY COL1 = 2 ASSIGNING <FS>.
<FS>-COL2 = 100.
READ TABLE ITAB WITH TABLE KEY COL1 = 3 ASSIGNING <FS>.
DELETE ITAB INDEX 3.
IF <FS> IS ASSIGNED.
WRITE '<FS> is assigned!'.
ENDIF.
LOOP AT ITAB ASSIGNING <FS>.
WRITE: / <FS>-COL1, <FS>-COL2.
ENDLOOP.
The output is:
1 1
2 100
4 16
