Unicode Fragment View
The Unicode fragment view splits a structure into fragments. A fragment
is a grouping of structure components of the same or similar data types.
In nested structures, the elementary components on the lowest nesting
depth are taken into account when forming fragments in nested
structures. The following parts of a structure are each grouped to form
fragments:
Consecutive flat character-like components of
the types c , n , d , and t , between which
there are no alignment gaps , form
character-like fragments.
Consecutive flat byte-like components of the type x , between
which there are no alignment gaps, form byte-like fragments.
Consecutive numeric similarly typed components of type ( b , s
), i ,
int8 ,
decfloat16 , decfloat34 , or f , between which there
are no alignment gaps, each form a separate fragment.
Each individual numeric type p component forms a separate
fragment. For this type of fragment it is the length that is important,
not the number of decimal places.
In deep structures, each deep component
(reference) forms a separate fragment.
Each alignment gap is regarded as a fragment.
Notes
In nested structures, alignment gaps can arise before and after aligned
substructures.
When structure components are passed using
INCLUDE , an additional alignment gap can appear in front of the
passed components.
The Unicode fragment view of structures with components of type p
can match, even when the number of decimal places in the components
concerned is different.
Example
DATA:
BEGIN OF struc,
a TYPE c LENGTH 3,
b TYPE n LENGTH 4,
c TYPE d,
d TYPE t,
e TYPE decfloat16,
f TYPE x LENGTH 2,
g TYPE x LENGTH 4,
h TYPE i,
i TYPE i,
j TYPE i,
k TYPE i,
END OF struc.
The structure struc contains the following Unicode fragments in a
Unicode system in which character-like fields are represented by 2 bytes
per character. Alignment gaps are marked with an A .
