Question

Is there another way to concatenate in ABAP instead of using the CONCATENATE keyword?

An example using CONCATENATE:

DATA:
  foo    TYPE string,
  bar    TYPE string,
  foobar TYPE string.

  foo = 'foo'.
  bar = 'bar'.

  CONCATENATE foo 'and' bar INTO foobar SEPARATED BY space.

Answer 1

You can (starting with ABAP 7.02) use && to concatenate two strings.

Data:
foo    TYPE string,
bar    TYPE string,
foobar TYPE string.

foo = 'foo'.
bar = 'bar'.

foobar = foo && bar.

This also works with character literals:

foobar = 'foo' && 'bar'.

For preserving spaces, use this kind of character literal named "text string literal" which is defined with two grave accents (U+0060):

foobar = foo && ` and ` && bar
