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.
