How to compress bar

In Easy language how to compress bars with a specific interval. Is there any function available to do that?

 

What do you mean by "compress bars"? Can you give an example? Thanks

 

Thanks for your reply,abattia
In amibroker the bars can be compressed using the function timeframeset. After working with the bar then time frame can be restored. Is it possible to do that in EasyLanguage?
