Insert a string at particular location in the internal table

Question

1. I have an internal table t_text of type bcsy_text , this internal table contains a few lines of HTML code
2. I have a variable w_text of type string , this variable contains some text
3. now the internal table t_text contains text:
<!"<font size = "3.5" ><b>Comments:</b></font><br><br>***********<br><br><font size = "3.5" ><b>Thank You</b></font>">
4. The text in the w_text comes from a text area on my module pool screen
5. There is a push button SAVE on the same module pool screen
6. now when I enter text in the text area and press the SAVE button then i want the text in the variable w_text to be inserted into the internal table at the location where i have marked *********** in my HTML code.
How do i achieve this?
<!-- **--> is not part of my HTML code.. i have written it because the HTML formatting appears on the screen if i dont comment it

Answer 1

Ankit,
You have to first determine which row of the internal table needs to be updated. Once you know which row, read that row into a variable using the READ statement and INDEX option.
Once you have the row in a variable (WA_ROW) , you have to determine the position where you want to insert the w_text contents.
Suppose that position is 123. Then, you can concatenate the first part of the row, w_text contents, and second part of the row into another variable (WA_NEW_ROW).
CONCATENATE wa_row(123)
w_text
wa_row+123
INTO wa_new_row
SEPARATED BY SPACE.
Finally, modify internal table contents with WA_NEW_ROW using the INDEX option.
