where are built-in functions for string processing kept?

Former Member — Mon, 07 Jan 2013 13:52:03 GMT

I am wondering where all these buil-in functions or methods for string processing are stored?

We genrally use many of the ABAP functions like lines( <itab> ) to get the number of lines present in internal table or say any mathematical function like ABS, ROUND etc.

We are calling these functions as we call private functional methods in public methods of any object.

So my question is what are these inbuilt funtions? Are they some Function module or is there any object which is global and available to all the development objects in ABAP and these static methods or public methods of this object?

Hi Mohammed,

These are called predefined functions and are part of the syntax of the ABAP language just as predefined data types are part of the language. You can read more about predefined functions in the ABAP keyword documentation.

Cheers,

Amy

Thanks very much Amy.
But i was woundering where these predefined functions are kept like in the form of a library?

Like there are SAP Components library there should be some library of functions where we can add our own funtions to it or enhance the existing ones. Like we have BREAK and CONTINUE statements which are stored as Macros in table TRMAC.
