Hi all,
I've a doubt in usage of EVALUATE.
In which case we can use EVALUATE and in which case we can use if.
Which one is more effective in basis of performance?

Regards,
Bipin Peter

the better way to use Evaluate when your are going to handle the more than 2 or 3 Condition ..

IF you can use where there ARE only 2 or three condition.

Evaluate is an easily understandable replacement for Nested-IF conditions.

Evalutate is mostly useful at the time of Nested-IF conditions,

When in your program more that 3-4 conditions u have to handle then it is good option to replace IF with Evaluate condition.

Hi Bipin,

I would rather ask - why would this be your concern ? Did you try something & it didn't work out ? What research you have done so far ?

if you have a question about what instruction is more efficient, why do you not look at the object code generated (can be found in compile listing).

"Which one is more effective in basis of performance?"
Although still important in a few specific cases, due to CPU speeds nowadays, I'd be more concerned with readability (maintainability) than saving a few microseconds of time.
