Source Code

    DATA txt(8) TYPE c VALUE '20050606'.

    DATA mytype(1) VALUE 'X'.


    ASSIGN txt TO <fs>.

<span class="blue">* correct --------------------------------------------------------------</span>

    ASSIGN txt TO <fs> CASTING TYPE d.
    WRITE / <fs>.

    ASSIGN txt TO <fs> CASTING TYPE (mytype).
    WRITE / <fs>.

<span class="blue">* obsolete, not allowed in methods -------------------------------------</span>

    "ASSIGN txt TO <fs> TYPE 'D'.
    "WRITE / <fs>.

    "ASSIGN txt TO <fs> TYPE mytype.
    "WRITE / <fs>.


This example demonstrates casting on predefined data types. First the character string txt is assigned to the field symbol <fs> without casting. Then txt is assigned to <fs> using casting on types d and x. The format of the second output row depends on the data in the user master record. The paired numbers in the last output row represent the hexadecimal code for the character in txt and depend on the character display of the current application server.

The syntax for the corresponding obsolete casting is still included in the commented out section of the method.
