catch exception when dividing zero

[Former Member]

As known, you can catch this error by using  'cx_sy_arithmetic_error'.

My question is, is it possible to do it without try catch.

I have tried, if you just use sy-subrc, it would cause a dump.

Hi Ming

So why do you want to bypass this standard code?

Actually, I am telling a develop who came from Java that sy-subrc/raise exception is better than try catch in easily reading.

But there might be some places where sy-subrc cannot be used like dividing zero.

Hi Ming,

Otherwise you can place a condition checking whether divisor variable is holding value zero or not. If divisor value is not equal to 0, then only do the division.

Sample:

IF LV_DIVISOR <> 0.

     LV_QUOT = LV_DIVIDEND / LV_DIVISOR.

ENDIF.

I would say that this is bad advice for you to give....  TRY-CATCH is the best approach for many scenarios, and with the increased use of exception classes (the recommended exception handling approach for class based development) it becomes more and more common.

I know that try catch is becoming common and it's has more function because it's class-based.

However, since most of methods have exception, especially if you want the logic as strict as possible. Then you will find you code are full of TRY & CATCH. It's not convenience to code and read. Compare this:

In Java:

try

{

call method;

}

catch (xxxException)

{

//handl exception

}

In ABAP

call FM or method.

case sy-subrc.

endcase.

I preffer the ABAP way.

Hi Ming,

View the code.

DATA lv_val TYPE P.

CATCH SYSTEM-EXCEPTIONS conversion_errors = 1

                                                   arithmetic_errors   = 5.

lv_val   = 100 / 0.

ENDCATCH.

Hope it helpful.

Thank you.

It's the one which I am looking for.

[PeterJonker]

And you just ignore the message about obsolete syntax ?

Well.......................... I better say nothing.

Let SCI do it for us, with some luck someone activated it at transport request release...

[Former Member]

I saw it. I am not saying I will use this.

I am just looking for the way that traditional ABAP does this.

Anyway, thank you for you remind.
