>- Especially in older ABAP programs, you will see other forms of the
`SELECT` syntax that you should no longer use. Strict syntax check modes might enforce the use
of specific ABAP SQL syntax. For example, the `INTO` clause should be placed after the other clauses. Furthermore, [host variables](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenhost_variable_glosry.htm "Glossary Entry") or [host expressions](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenhost_expression_glosry.htm "Glossary Entry") are required for data objects and expressions, i. e. they must be preceded by `@` or `@( ... )`.
