R).SY-UCOMM- Function code that triggered the event PAI.Every user action that triggers PAI is assigned a unique function code, with one exception:Choosing ENTER triggers PAI and different function codes can be transferred to SY-UCOMM:

·  a).If there is an entry in the command field of the standard toolbar, this is transferred to SY-UCOMM as the function code.

·  b).If there is no entry in the command field and a function code is assigned to the ENTER key, this function code is transferred to SY-UCOMM.

·  c).If the command field does not contain an entry and no function code is assigned to the ENTER key, it is empty and the content of SY-UCOMM is not affected.

S).SY-LINCT- Page length of list.SY-LINCT is 0 for a standard list of any length and has a value unequal to 0 for lists with fixed page length.

·  a).LINE-COUNT in the statements REPORT, PROGRAM, FUNCTION POOL sets SY-LINCT for the current program.

·  b).LINE-COUNT in the SUBMIT statement sets SY-LINCT for the called program.

T).SY-LINNO- Current row during the list creation.Counting begins at 1 and includes the page header.SY-LINNO is set by the following output statements:

·   a).WRITE, ULINE, SKIPraise SY-LINNO by 1 in the case of a line break.

·   b).BACK sets SY-LINNO to the first row after the page header.BACK in connection with RESERVE sets SY-LINNO to the first row of a block of lines.

·   c).NEW-LINE raises SY-LINNO by 1.

·   d).SKIP TO LINE lin sets SY-LINNO to lin.If lin does not lie between 1 and the page length, the system ignores the statement.

U).SY-LINSZ- Line width of list Without further influence this is the standard window width: If SY-SCOLS >= 84, SY-LINSZ = SY-SCOLS; if SY-SCOLS < 84, SY-LINSZ = 84.  

To change the width of the output list, use the LINE-SIZE option of the REPORTor NEW PAGE statement.

·   a).LINE-SIZE in the statements REPORT, PROGRAM, FUNCTION POOL sets SY-LINSZ for the current program.

·   b).LINE-SIZE in the SUBMIT statement sets SY-LINSZ for the called program.

V).SY-LILLI- Line from which the event was triggered Counting begins at 1 and includes the page header.

W).SY-LISEL- Contents of the line from which the event was triggered.

X).SY-LSIND- Index of the list that is being created (basic list: 0, detail list > 0).Each time an interactive list event occur, the system automatically increase SY-LSIND by 1.SY-LSIND can be changed in the ABAP program to navigate between detail list.Change to SY-LSIND are not taken into account until the end of the list event.Therefore, any manipulation of SY-LISND shouldbedone usingthelast commandofthe processing block.
