Check if string is numeric

[Former Member]

FORM IsNumeric.

DATA:   numeric(10) TYPE C VALUE '0123456789 ',
             account(10) TYPE C VALUE '600',
             rc TYPE C.

  IF account CO numeric.
      rc = ''.
  ELSE.
      rc = 'X'.
  ENDIF.
ENDFORM.

The result is  rc = 'X'

Where I'm wrong?

Hi,

your variable account(10) TYPE C VALUE '600'. Is of length 10 so account is actually '       600' i.e. with 7 spaces in the value. but your string '0123456789 ' does not have space as the length is 10 so the space is truncated, so numeric = '0123456789' all total 10 chars the space is missing due to length. If numeric is of length 11 it will work.

Try this code .

DATA:   numeric(10) TYPE C VALUE '0123456789 ',

             account(3) TYPE C VALUE '600',

             rc TYPE C.

  IF account CO numeric.

      rc = ''.

  ELSE.

      rc = 'X'.

  ENDIF.

ENDFORM.

Mio,

If the value for account was '0000000600' your code will work fine. Try as per below:

DATA:   numeric(10) TYPE C VALUE '0123456789 ',

             account(10) TYPE C VALUE '600',

             len type char10,

             rc TYPE C.

  condense account.

   len = strlen ( account ).

  IF account+0(len) CO numeric.

      rc = ''.

  ELSE.

      rc = 'X'.

  ENDIF.

This should solve your issue.

Thanks,

Hi,

you can see this example:

   REPORT  z_check_string.


DATA:  account(10) TYPE c VALUE '2001',
             rc TYPE c,
             lung TYPE i,
             pos TYPE i,
             char(1).


lung = strlen( account ).
DO lung TIMES.
  char = account+pos(1).
  IF char CO '0123456789'.

*here if you want you can move char into others flow..............
  ELSE.
    rc = 'X'.
    EXIT.
  ENDIF.
  pos = pos + 1.
ENDDO.

WRITE rc.

I hope that this example helped you and solve your issue.

Regards

To make use of more modern ABAP I'd rather write:

DATA:   numeric(11) TYPE C VALUE '0123456789 ',   "as suggested by arindam

             account(10) TYPE C VALUE '600',

             rc TYPE C.

rc = boolc( account CO numeric ).

boolc returns a boolean for the given expression.
