What will be the value of 'var' after the statement CLEAR var, if it was initially set to 100?

The statement CLEAR var is used to reset the variable 'var' to its initial value, which depends on the type of 'var'. In the context of numeric types, the initial value is typically 0. Therefore, after executing CLEAR var, the value of 'var' changes from 100 to 0.

This behavior reflects how the CLEAR statement works in ABAP. It effectively initializes the variable to its default state, ensuring that for numeric types, it will represent zero. For other types, such as character strings, the initialization would result in an empty string, but since 'var' is numeric in this scenario, the outcome is 0.

Understanding this functionality is important for ensuring that variables are properly re-initialized before being used, particularly within loops or conditional structures where previous assignments might influence program logic.
