如何在字符串中加入回车换行，tab字符

Answer 1

CL_ABAP_CHAR_UTILITIES 中有字符常量:如:CR_LF,HORIZONTAL_TAB,NEWLINE等等.
下面给出字符串中加入回车换行的示例:
DATA: crlf(2) TYPE c.
DATA: l_html(4096) TYPE C.
crlf = cl_ABAP_char_utilities=cr_lf.
CONCATENATE l_html crlf '_FUNCTION''30''WWW_GET_REPORT' '' INTO l_html.
string的标准函数查找:FIND [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF] pattern IN dobj替换:REPLACE [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF] pattern IN dobj WITH new
REPLACE SECTION [OFFSET off] [LENGTH len] OF dobj WITH new移动:SHIFT c [BY n PLACES] [mode]拼接:CONCATENATE c1 ... cn INTO c [SEPARATED BY s]分割:SPLIT c AT del INTO c1 ... cn.
大小写转换:
TRANSLATE text TO UPPER CASE.
TRANSLATE text TO LOWER CASE.
字符串覆盖:
OVERLAY c1 WITH c2 [ONLY str].
压缩字符串:

Answer 2

字符串中加入回车换行的示例:
DATA: crlf(2) TYPE c.
DATA: l_html(4096) TYPE C.
crlf = cl_ABAP_char_utilities=>cr_lf.
CONCATENATE l_html crlf '_FUNCTION'
'30'
'WWW_GET_REPORT' '>' INTO l_html.
string的标准函数
查找: FIND [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF] pattern IN dobj
替换: REPLACE [{FIRST OCCURRENCE}|{ALL OCCURRENCES} OF] pattern IN dobj WITH new
REPLACE SECTION [OFFSET off] [LENGTH len] OF dobj WITH new
移动:SHIFT c [BY n PLACES] [mode]
拼接:CONCATENATE c1 ... cn INTO c [SEPARATED BY s]
分割:SPLIT c AT del INTO c1 ... cn.
大小写转换:TRANSLATE text TO UPPER CASE.
TRANSLATE text TO LOWER CASE.
字符串覆盖:OVERLAY c1 WITH c2 [ONLY str].
压缩字符串:CONDENSE c [NO-GAPS].

看语言，语言不同写法不同。
