Hi Henry,

this will be run:

( set hide behind write)

DO 5 TIMES.

WRITE: / sy-index.

HIDE sy-index."<----

---

ENDDO.

AT LINE-SELECTION.

WRITE sy-index.

Hi ,

I don't think set hide behind write is the only problem.If you removed <b>/</b> in write statement,we won't get desired result.

• Check this it won't work

DO 5 TIMES.

WRITE: sy-index.<b>"<--check here-</b>

HIDE sy-index.

ENDDO.

AT LINE-SELECTION.

WRITE sy-index.

So either if you want to use hide behind write , you should use <b>/</b> in write as Andreas mentioned.

Or you should use skip or Uline command as I suggested.

Anyway you cannot write everything in same horizontal line.

Output should be vertical .

Hi Henry,

from Abap-docu:

...

HIDE <f>.

This statement places the contents of the variable <f> for the current output line (system field SY-LINNO) into the HIDE area. The variable <f> must not necessarily appear on the current line.

To make your program more readable, <b>always place the HIDE statement directly after the output statement</b> for the variable <f> or after the last output statement for the current line.

...

have a look here:

Hi Henry,

As I already replied,it is because in your original code you mentioned the sy-index to be in the same line.

Usually,the purpose of AT Line-selection is pick that line.That's why it is taking the sy-index in your code as 5.

But in my code and Andreas code , we are displaying the output vertically.

And in the below mentioned code,I think while processing write statement itself since it needs to process both sy-index and '/' , it is incrementing sy-index by one.

do 3 times.

hide sy-index.

write : / sy-index.

enddo.

at line-selection.

write sy-index.

Write sy-index and Hide should be consecutive.

The behaviour of write 😕 sy-index is it first process / and then sy-index.

In Andreas coding, he has written write and then hide.

While processing the write 😕 sy-index, it is first processing hide and then / and then sy-index.

In my coding, I have written hide and then write(without /).Here also it is consecutive.

But in the coding you mentioned , you have written hide and then write (with /).It is processing hide and then / and then sy-index.In this case Hide and Write sy-index are not consecutive.That's why you get the output incremented by one.

Hope this is clear.

For more information about HIDE and At Line-selection,check this.

http://www.sts.tu-harburg.de/teaching/sap_r3/ABAP4/hide.htm

Check this also.It will also work fine since write sy-index and Hide are consecutive.

do 3 times.

hide sy-index.

write sy-index.

new-line.

enddo.

at line-selection.

write sy-index.
