It's a beautiful thing, the Destruction of words. Of course the great wastageis in the verbs and adjectives, but there are hundreds of nouns thatcan be got rid of as well.—George Orwell, 19842 New Language Features in ABAP 7.4Back in the early eighties, when I was st ill a teenager, my parents bought me aBBC Microcomputer to replace my ZX81. Even then, my primary interest wasprogramming as opposed to playing games, and what I liked most about my newtoy was the broad range of commands that were then available to me in the BBC’sversion of BASIC (for example, constructs such as REPEAT UNTIL ). Even now,many years later, I look on with interest when something is added to the ABAPlanguage.As time has gone by, more and more commands and constructs have been addedto ABAP—while nothing has been taken away, to ensure backward compatibility—andthe rate of change seems to be violently accelerating. A fair number ofchanges came in as a result of the in troduction of SAP NetWeaver 7.02, whichthis chapter will touch on, but this is nothing compared to the cascade of changesthat came with version 7.4. This proves beyond a doubt that ABAP is not a deadlanguage, which was a fear of many peop le in 2001, when there was talk (fromthe very top of SAP) about replacing ABAP with Java.The quote at the beginning of the chap ter from George Orwell’s novel 1984 isabout the destruction of words. The ch aracter working on the language “Newspeak”says to the main character, Winston Smith, that the ruling party is hell-benton destroying existing words, as opposed to creating new ones. The idea of ABAP7.4 is, in some ways, the same: Many of the 7.4 changes allow you to achieve theexact same tasks as before, but with half the code or less. For example, in Newspeak“that was wonderful, fantastic, th e best thing ever” becomes “++good.” InABAP, CONCATANATE ld_this ld_that INTO ld_the_other SEPARATED BY ‘_’becomes ld_the_other = ld_this && ‘_’ && ld_that.81
