Abap字符转ASCII

1．字符转ASCII
   URL_ASCII_CODE_GET

特点：根据这个算法可以中文转ASCII

DATA: char_cd(2) TYPE c.

CALL FUNCTION 'URL_ASCII_CODE_GET'
  EXPORTING
    trans_char = 'A' 
  IMPORTING 
    char_code = char_cd.

WRITE /: char_cd.

 

2. 利用cl_rpe_convert字符与ASCII互转

DATA: str   TYPE string ,
      xstr  TYPE xstring,
      l_con TYPE REF TO cl_rpe_convert .

START-OF-SELECTION.

CREATE OBJECT l_con.

CALL METHOD l_con->string_to_xstring
  EXPORTING
    input = 'ABC'
  IMPORTING
    output = xstr.

CALL METHOD l_con->xstring_to_string
EXPORTING
  input = '426172727942'
IMPORTING
  output = str.

WRITE / : xstr ,str.

 

3. 特殊字符处理 利用类CL_ABAP_CHAR_UTILITIES在字符串中加入tab字符，回车换行符，换页符

DATA: str   TYPE string ,
      xstr  TYPE xstring,
      l_con TYPE REF TO cl_rpe_convert .

START-OF-SELECTION.

CREATE OBJECT l_con.
str = cl_abap_char_utilities=>cr_lf.

CALL METHOD l_con->string_to_xstring
EXPORTING
input = str
IMPORTING
output = xstr.

CALL METHOD l_con->xstring_to_string
EXPORTING
input = '4213'
IMPORTING
output = str.

WRITE / : xstr ,str.
