Assignments, Calculations, and Other Types of Data Access

During an assignment, the content of a data object is transferred to another data object. If the data objects are compatible, the content is copied unchanged. If the data objects are incompatible and there is a suitable conversion rule, the content is converted. An assignment is usually performed with the assignment operator (=).

A calculation is executed in a calculation expression, which can be shown in an operand position or on the right side of the equals sign of the COMPUTE statement. If necessary, the result of a calculation expression is converted to the data type of the operand position or of the result of the COMPUTE statement. In arithmetic expressions, the calculation is executed in a calculation type based on the data types of all operands including the result.
