转:在ABAP中实现进度条的例子

小弟在做一个项目时用户提出程序运行时显示进度条的问题，加之本人以前也碰到这种需要求，所以按以前在WIN32下的编程经验，设计了一个进度条显示INCLUDE程序。这个程序可以显示条状进度条以及进度百份比，并可以显示注释，现将代码COPY如下：

*&---------------------------------------------------------------------*
*& Include ZSHOWMES *
*&---------------------------------------------------------------------*
*& Author : wuping *
*& Create Date : 2006-05-17 *
*& Program Type : Report *
*& SAP Release : 4.7C *
*& Description : 用来做信息类型 *
*&---------------------------------------------------------------------*

*&---------------------------------------------------------------------*
*& Form. SCHEDULE
*&---------------------------------------------------------------------*
* text
*----------------------------------------------------------------------*
* --> p1 text
* <-- p2 text
*----------------------------------------------------------------------*
form. schedule using
c_message type c
i_percent type i.
data: c_sche(204).

if i_percent <= 0 or i_percent > 100 .
c_sche = '百分比错误!!!'.
else.
data: c_percent(4),
c_block(6) type c value '■■',
i_blocklen type i,
i_count type i,
i_col type i,
i_len type i,
i_temp type i value 0,
i_mod type i.
i_blocklen = strlen( c_block ).
c_percent = i_percent.
condense c_percent.
c_percent+3(1) = '%'.
c_sche = c_percent.
i_count = i_percent / 4.
do i_count times.
i_col = ( i_temp * i_blocklen ) + 4.
c_sche+i_col(i_blocklen) = c_block.
i_temp = i_temp + 1.
enddo.
i_len = strlen( c_message ).
i_mod = i_len mod 2.
if i_mod = 1.
i_len = i_len + 1.
endif.
if i_len > 0.
c_sche+4(i_len) = c_message.
endif.
i_len = strlen( c_sche ).
endif.
call function 'SAPGUI_PROGRESS_INDICATOR'
exporting
percentage = 0
text = c_sche
exceptions
others = 1.
endform. " SCHEDULE

以下是调用这个INCLUDE的示例程序：
*&---------------------------------------------------------------------*
*& Report ZTEMP_8 *
*& *
*&---------------------------------------------------------------------*
*& *
*& *
*&---------------------------------------------------------------------*

report ztemp_8 .
include zshowmes.
data: i_prog type i,
i_prog2 type i.

START-OF-SELECTION.
do 100 times .
do 100000 times.
i_prog2 = i_prog2 + 1.
enddo.
i_prog = i_prog + 1.
write: / '第' no-gap , i_prog no-gap , '次运行:',i_prog2.
perform. schedule using '' i_prog. "调用上面的INCLUDE显示进度
enddo.
