Conversion Rules for Structures

This example demonstrates how structures can be converted from one type to another.

Source Code

    DATA: BEGIN OF fs1,
             int   TYPE i            VALUE 5,
             pack  TYPE p DECIMALS 2 VALUE '2.26',
             text  TYPE c LENGTH 10  VALUE 'Fine Text',
             float TYPE decfloat16   VALUE '1.234e+05',
             date  TYPE d            VALUE '19950916',
          END OF fs1.

    DATA: BEGIN OF fs2,
             int  TYPE i            VALUE 3,
             pack TYPE p DECIMALS 2 VALUE '72.34',
             text TYPE c LENGTH 5   VALUE 'Hello',
          END OF fs2.

    WRITE: / fs1-int, fs1-pack, fs1-text, fs1-float, fs1-date.
    WRITE: / fs2-int, fs2-pack, fs2-text.

    MOVE fs1 TO fs2.
    WRITE: / fs2-int, fs2-pack, fs2-text.

Description

In this example two different structures are defined, fs1 and fs2. The requirements of the third conversion rule for flat structures apply to both structures and the corresponding rule is also used. After the assignment of fs1 to fs2, only the result for the first two components is as if they had been transferred component by component. fs2-text is filled with the first five positions from fs1-text. All the remaining elements of fs1 are not transferred.
