[line_properties]:

[VALUE val] [LENGTH len] [[DISPLAY|MEMORY] OFFSET off].

获取光标

 

4.Printing Lists

          打开Print,

1.使用NEW-PAGE PRINT ON；

2.Excute+Print;

3.SUBMIT program TO SAP-SPOOL;

4.排程job，使用VIA JOB and TO SAP-SPOOL；

          print参数

1.打印dialog

通过function: SET_PRINT_PARAMETERS, GET_PRINT_PARAMETERS，设置和获取打印参数；

2.打印控制

语法：

SET MARGIN macol [marow].

设置margin,行，列。设置系统sy-macol,sy-marow。

语法：

PRINT-CONTROL { { formats|{FUNCTION code}  [LINE line] [POSITION col] }
