detect asterisk from parameter (user input)

Former Member — Fri, 24 Jul 2009 05:13:08 GMT

Hi all,

How do you detect asterisks from an inputted parameter of type string?

The user is supposed to use asterisks on the left, right, or both sides of the word/s that they type in the parameter field.


Parameters: p_txt50 type string.

This is what i want to do:
If p_txt50 has asterisk to the right (ex. computer*)
[code goes here]
If p_txt50 has asterisk to the left  (ex. *computer)
[code goes here]
If p_txt50 has asterisk on both sides  (ex. *computer*)
[code goes here]
Thank you very much :)

Hi,

U can Do it using String Operations.

Try using CP (Contains Pattern ).

Hi,

You can achieve it using

CP - Contains Pattern or

NP - Contains No Pattern

Thanks,

Sri.

Thank you for the replies. I found the CP documentation, but I couldn't find how to use it properly.

Can you elaborate more (on the actual syntax) that I could use?

if p_text CP '*'. " This means ur parameter has any * then execute ur code

your code.

endif.

Here param is the parameter name in ur program.

Hi,

Try Like below;

Data : lv_len type i.

lv_len = strlen( p_txt50 ).
lv_len = lv_len - 1.
if p_txt50+0(1) EQ '*' AND p_txt50+lv_len(1) EQ '*'.
"Contains Asterik in both sides.
else if p_txt50+0(1) EQ '*' AND p_txt50+lv_len(1) NE '*'.
"Contains Asterik in front
else if p_txt50+0(1) NE '*' AND p_txt50+lv_len(1) EQ '*'.
"Contains Asterik in last
endif.

Check this and revert back.

Regards

Hi,

Do as below

DATA : l TYPE i.

PARAMETERS : p_var50 TYPE string.

AT SELECTION-SCREEN ON p_var50.

  l = STRLEN( p_var50 ).
  l = l - 1.

START-OF-SELECTION.

  IF p_var50+0(1) = '*' AND p_var50+l(1) = '*'.

    WRITE : 'Both ends'.

  ELSE.
    IF p_var50+0(1) = '*'.

      WRITE : 'Starting'.

    ELSE.
      IF p_var50+l(1) = '*'.

        WRITE : 'End'.

      ENDIF.
    ENDIF.

Also, you will have to use -

> strlen(variable) to check the string length..

and str1 = str2+2(5).

What you can do is...

1) to check whether the last char is '*', calculate string length, minus 1 from it(v1), and put in the statement..

str1 = str2+v1(v2) " where v2 = 1.

now check whether it's '*' or not in str1.

2) Use similar logic for

syntaxes for string manipulations..

Exactly as Kartik has suggested!

Hi,

Use SEARCH Statement. Refer Following code

SEARCH p_text FOR '*'.

IF sy-subrc EQ 0.

ENDIF.

DATA: f1(5) TYPE c VALUE 'aBcde',

      f2(5) TYPE c VALUE '*b*'.

IF f1 CP f2 .
   WRITE: /  'Value found, SY-FDPOS=', sy-fdpos.
ELSE.
   WRITE: /  'Value not found, SY-FDPOS=', sy-fdpos.
ENDIF.

Hope this clears the issue.

Thanks

HI,

Declar two variables say var1 and var2. Now check if the first character of the entered string is * and the last character is * then process the code when fisrt and last characters are *, else check if only fist character is * or last character is *.

Following is s pseudo code


var1 = p_txt50(0)+1.
v_len = strlen( p_txt50  ).
v_len = v_len - 1.
var2 = p_txt50(v_len)+1.
if var1 = '' and var2 = '*'.
insert code for *computer*
elseif var1 = '*'.
insert code for *computer
elseif var2 = '*'.
insert code for computer*.
else
insert code for non of the abpve condition.
endif.

Hope this helps.

Regards,

Sachin
