本文介绍了通过ABAP编程中的HIDE、READLINE、GETCURSOR及DESCRIBELIST等语句，在交互式事件中从报表行向处理块传递个别输出字段或额外信息的方法。这些技术有助于更灵活地控制数据展示和后续处理。

Passing Data by Program Statements

To pass individual output fields or additional information from a line to the corresponding
processing block during an interactive event, use these statements:

HIDE
The HIDE statement is one of the fundamental statements for interactive reporting. You
use the HIDE technique when creating a basic list. It defines the information that can be
passed to subsequent detail lists.

READ LINE
Use the statements READ LINE and READ CURRENT LINE to read data from the lines
of existing list levels. These statements are closely connected to the HIDE technique.

GET CURSOR
Use the statements GET CURSOR FIELD and GET CURSOR LINE to pass the output
field or output line on which the cursor was positioned during the interactive event to the
ABAP program.

DESCRIBE LIST
The DESCRIBE LIST statement allows you to read certain list attributes, such as the
number of lines or pages, into program variables.
