Avoid EQ for performance

Hi All,

I am intermediate in ABAP programming i have seen in many other site and in some scn discussion that use '=' symbol instead of 'EQ' for better performance.So i want to what is the logic behind it ?

In my opinion there is absolutely no difference.

Hi,

since processors are getting more and more powerful, I doubt there will be much difference in terms of performance. I would rather focus more on the programming logic/codes to better retrieve the data from the database.

My 2 cents.

Hi,

I searched ASCII chart in ABAP, and saw that '=' has a direct ASCII value assignment but i did not find 'EQ' in ASCII chart. So maybe there's some conversion from EQ to '=' and then ASCII.

Regards,

I agree.

Absolutely no difference in terms of program execution.

The difference, extremely small, could be at the time code gets compiled.
