Description

The class demo contains an attribute for every predefined ABAP type and for time stamps. These attributes are filled with example values and assigned to a data object by WRITE TO. The length of this data object can be chosen on the selection screen.

The country-specific formats for numbers, dates, and times set by SET COUNTRY can also be specified on the selection screen. This example demonstrates these formats as well.

The output list shows the result of the formatting for each data type. If an exception is raised, the character "!" is highlighted in a different color.
