ASCII Character Processing in ABAP

[Former Member]

Hi,

I have to remove the special characters (+/-, Ø) from the Text and process the same with out the Special Characters in it. The General requirement is that, I need to remove the special characters, which fall between the ASCII Values 32 to 128. Is there a Standard Function Module or Function available in SAP. Can you please suggest me a good solution for this requirement. Thanks for your Help in Advance.

Thanks and Regards,

Kannan.

i dont know exactly is there any function module available,but here i am giving small logic,may be helpful to you.

you can use REPLACE command to replace the special characters with some space.

data : V_CHAR(100) type c.

<b>REPLACE ALL OCCURRENCES OF ',' IN V_CHAR WITH ''.</b>

THEN use CONDENSE To remove the spaces between the characters.

<b>CONDENSE V_CHAR.</b>

Hi Srikanth,

Thanks for the reply. Actually i have to look for the Special Characters which has ASCII Values between 32 to 128. So in each Text, i have to check for the occurance of 96 Special Characters. There may be one or more special characters that exists in the Text.

Thanks and Regards,

Kannan.

Hi!

I don't think there is a function module for such a task - everyone might understand something different under 'special character'.

But you can use the ABAP-statement TRANSLATE text USING pattern. In pattern you can define pairs of characters as a replacement-rule, just have a look into the online help.

You might run into a problem defining all the source-values, maybe you can use hex-defined structures as a help variable.

Hi,

DATA: v_char.

FIELD-SYMBOLS: .

IF v_int1 IN r_hex.

CONCATENATE v_result v_char INTO v_result.

CONDENSE v_result.

ENDIF.

ENDDO.

WRITE: / v_result.

Hope this helps..

Thanks,

Hi Naren,

Please have a look at the link below.

http://www.lookuptables.com/. The good ones are from 32 to 127. Rest of them are giving problem. Please also look the extended ASCII Codes. 0 - 31 and 128 - 255 are the problem ones. The objective is not to allow them in the Text. Please let me know your thoughts.

Thanks and Regards,

Kannan.

THe following codereplaces special chars ( < 33 and > 127 ) with space.

data: len type i,
      off type i,
      hex1 type x value '1F',
      hex2 type x value '80'.

data asci_str(100) type c.

field-symbols <fs> type any.

len = strlen( asci_str ).

while off lt len.
  assign asci_str+off(1) to <fs> casting type x.
  if <fs> le hex1 or <fs> ge hex2.
    asci_str+off(1) = ' '.
  endif.
  add 1 to off.
endwhile.

write:/ asci_str.
