Comparing Hexadecimal value in program

Former Member — Sat, 02 May 2009 11:43:14 GMT

Hi friends,

I have requirement in this I have to pick a file and have to write some logic by comparing file contents.

File contents some hexadecimal character like '#'.

When I am writing simple if condition like

if var = '#'.

---

endif.

It is not going in that if condition even when the var has value from # from file. so i think as it is hexadecimal value there is some other way to compare it.

Please let me know how can I compare hexadecimal value.

Indeed # is a character representation of a separator (tab or space) which is seen as # in character mode.

Use below snippet to compare it


DATA: xsep TYPE xstring,
                sep TYPE string.

              xsep = '09'. "if separator is tab mark
              xsep = '20'. "if it is space

          CALL FUNCTION 'HR_KR_XSTRING_TO_STRING'
            EXPORTING
              in_xstring = xsep
            IMPORTING
              out_string = sep.

         "now SEP contains character representation for separator (which is seen as #)
          "you can i.e. split uploaded file data (in iternal table) based on that separator
          SPLIT it_file_data AT sep INTO TABLE it_file_fields IN CHARACTER MODE.

          "for comparing use
          if var = sep.
              ...
          endif.

Hi Marcin

I tried the method u showed but its not working, I think that # symbol there represent line feed or carriage return and not space.

What is the value of line feed and carriage return, as 20 for space?

Hex:

Carriage return - '0D'

Newline (so called line feed) - 'A'

Char:

Carriage return and line feed - use CL_ABAP_CHAR_UTILITIES=>CR_LF

Only newline - CL_ABAP_CHAR_UTILITIES=>NEWLINE

Hi Marcin,

I was able to get the proper split value using hex decimal '0A'.

I got it from this link http://www.dynamoo.com/technical/ascii.htm

Thanks for your help...
