Only Unicode Systems in Release 7.50


ABAP 7.50 is Unicode only! An AS ABAP can only run as Unicode System with system code page UTF-16. All ABAP programs must be Unicode programs where the Unicode syntax checks are effective.You must always set the respective program attribute.




Nothing more to say from my side.


New Built-in Data Type INT8


The existing built-in types b, s, i in the ABAP language and the respective built-in types INT1, INT2, INT4 in the ABAP Dictionary got a big brother (or is it a sister?):


  • int8 in ABAP language and INT8 in the ABAP Dictionary.


  • They specify 8-byte integers with a value range of  -9223372036854775808 to +9223372036854775807.


Not much to say about that either. Simply go and use it if you need big integers. The rules are mainly the same as for 4-byte integers, of course with enhanced values for alignment requirement (adress must be divisible by 8), predefined output length on screens (20) and a new calculation type  int8 for arithmetic expressions.


Just a little example to remind you that it is always good to use an integer calculation type if you calculate integers, especially for big integers:
DATA arg TYPE int8 VALUE 2.

)->write( |** : { arg ** 62 }|
)->write( |ipow: { ipow( base = arg exp = 62 ) }|
)->display( ).


While ** calculates with floating point type f and produces a wrong result, ipow calculates with int8 and produces the correct result.


PS: Cool way of "writing" isn't it? But only for demo purposes ...
