Hi,

How can I search exactly for f+ in the

'xcdf+fdfrfv' ?

I get right here sy-subrc 0 and its wrong.

I am searching for f+ and not for f

Regards

sas

DATA: moff TYPE i,
      mlen TYPE i,
      s type string.

    s = 'f+'.

FIND REGEX s IN 'xcdfedfrfv'
     MATCH OFFSET moff
     MATCH LENGTH mlen.

Try this modified code.

DATA: moff TYPE i,

mlen TYPE i,

s type string.

s = 'f+'.

FIND s IN 'xcdf+edfrfv'

MATCH OFFSET moff

MATCH LENGTH mlen.

write : moff, mlen.

rwrd points if useful

+ Matches the preceding element one or more times. For example, f+ matches "f", "ff", "fff", and so on.

try s = 'f\+'

Karsten has solved the problem.

His answer is correctly. But this issue is not

solved completely unless the cascading problem

is not solved.

I must find out a way to prefix \ whether

somebody search e.g. f+.

privously -> s_input-low f+

later -> s_input-low f\+

data lv_string(20) type c.

select-options s_input for lv_string.


DATA: moff TYPE i,
      mlen TYPE i,
      s type string.

translate s_input-low TO LOWER CASE.


FIND REGEX s_input-low IN 'xcdfedfrfv'
     MATCH OFFSET moff
     MATCH LENGTH mlen.

parse the string and escape (\) everything that's not a char or a number or ...

or let the user decide how he want's to search (a lot of search dialog work in this way):

data lv_string(20) type c.

select-options s_input for lv_string.
PARAMETERS p_reg type c as CHECKBOX.


DATA: moff TYPE i,
      mlen TYPE i,
      s type string.

translate s_input-low TO LOWER CASE.

if p_reg is initial.
  FIND s_input-low IN 'xcdfedf+rfv'
       MATCH OFFSET moff
       MATCH LENGTH mlen.
else.
  FIND REGEX s_input-low IN 'xcdfedf+rfv'
       MATCH OFFSET moff
       MATCH LENGTH mlen.
endif.

write: moff, mlen.
