Executing a Arithmatic formula stored in Variable

[Former Member]

Hi all,

I need solution to execute a arithmatic operation which is stored in a variable.

For Example:

data : var type string.

var = ABS('-3').

Now by means of the variable var i need to get the absolute value of -3

ie my output should be 3 if i print the variable "var".

Please help.

Hello,

Do like this.

REPORT ZV_SDN_3 .
 
DATA: STR TYPE STRING.
DATA: STR1 LIKE STR,
      INT TYPE I,
      LEN TYPE I.
STR = ABS('-3')..
LEN = STRLEN( STR ).
DO LEN TIMES.
  IF NOT STR+INT(1) IS INITIAL.
    IF STR+INT(1) CA '0123456789'.
      CONCATENATE STR1 STR+INT(1) INTO STR1.
    ENDIF.
  ENDIF.
  ADD 1 TO INT.
ENDDO.


 
WRITE: STR1.

Hope this will solve ur issue.

Cheers,

Hi,

I think my example has little bit of misguidance . The real concept is the formula is stored in the string.

i.e var = 'ABS('-3')'.

Now if i display the variable var , I need the output as 3.

Please help.

Do what Rob says. It's the only solution I'm aware of.

You could generate ABAP code on the fly. Do F1 on GENERATE SUBROUTINE POOL.
