Let’s concatenate

We start with two variables:

DATA word1 TYPE string.
DATA word2 TYPE string.
DATA: phrase TYPE string.

word1 = ‘this’.
word2 = ‘that’.

And we want to concatenate them adding the word “plus” between them and, of course, separate them by space.

Form 1 (the classic):

CONCATENATE word1 ‘plus’ word2 INTO phrase SEPARATED BY space.

Form 2, which doesn’t leave a space between them:

phrase = word1 && ‘ ‘ && 'plus' && ‘ ‘ && word2.

Form 3, more far fetched but which separates the words:

phrase = word1 && ‘ALT+255‘ && 'plus' && ‘ALT+255‘ && word2.

(in which ALT+255 is really pressing ALT and then writing 255)
(it isn’t really a space but it looks the same)

Forma 4, the state of the art in concatenation:

phrase = | { word1 } plus { word2 } |.

Actually, this last one even lets you invoke methods directly:

phrase = | { o_book->get_word( 1 ) } plus { o_book->get_word( 2 ) } |.

Thank you Ricardo Monteiro for the ALT+255 trick and Sérgio Fraga for showing us the future.
Thank you halfrain for the photo.

    phrase = word1 && ‘ ‘ && word2.
    phrase = word1 && ` ` && word2. “this will keep space

    Single quotation mark should be different, but they are “parsed”/changed to other in this web. Check example in link (different kinds of quotation marks).

    One more comment :D

    Here I found direct help page about what I wanted to say:

    The thing is, that “Text string literals”(check link) keeps space. So by using them, modified example “Form 2” would work.

    Hi Thommas, indeed you’re right. I’ll soon update the article to reflect your findings.
