Former Member — Wed, 12 Feb 2014 15:45:20 GMT

hi all,

i want to insert # symbol before every character in my string. but only if the character is not a * .

eg: input = hello should give me

output = #h#e#l#l#o

input = *.hello should give me

output = *#.#h#e#l#l#o

How can this be coded. Thanks in advance

data : lv_length type i.

constants : lv_hash(1) VALUE '#'.

lv_length = strlen( input ).

DO lv_length times varying lv_char first input(1) next input(2).

iF lv_char <> '*'. .

CONCATENATE lv_string lv_hash lv_char INTO lv_string.

ENDIF.

ENDDO.

Hi Rojer, you can check this code.

DATA: l_times      TYPE numc4,
       l_index      TYPE numc4,
       l_string     TYPE string,
       l_new_string TYPE string,
       l_char.

l_string = '*.hello'.

l_times = STRLEN( l_string ).

DO l_times TIMES.

   l_char = l_string+l_index(1).

   IF l_char NE '*'.
     CONCATENATE l_new_string '#' l_char INTO l_new_string.
   ELSE.
     CONCATENATE l_new_string l_char INTO l_new_string.
   ENDIF.

   l_index = l_index + 1.

ENDDO.

Regard.

Hi Rojer,

This code will help you:

data: l_string TYPE string VALUE '*.HELLO',
        l_char VALUE '#',
        l_ast VALUE '*',
        l_string_aux TYPE String,
        l_longitud TYPE i,
        l_counter TYPE i.

l_longitud = strlen( l_string ).

** '*HELLO'
WHILE l_counter <= ( l_longitud - 1 ).

   IF l_string+l_counter(1) NE l_ast.
     CONCATENATE l_string_aux l_char l_string+l_counter(1) INTO l_string_aux.
   ELSE.
     CONCATENATE l_string_aux l_string+l_counter(1) INTO l_string_aux.
   ENDIF.

   l_counter = l_counter + 1.

ENDWHILE.

WRITE l_string_aux.

----------------------------------------------------------------------------------------------

Example with string = '*.HELLO'.

Example with string = 'HELLO'.

Best regards

Here is a one-liner regex way to do it. Isn't that smooth?


DATA lv_str TYPE string VALUE '*.hello'.
REPLACE ALL OCCURRENCES OF REGEX '([^*])' IN lv_str WITH '#$1'.
WRITE lv_str.
