This constant determines whether the osOpenTimer function is included or excluded during the compilation process. The function is compiled into the system when this value is set to 1 and is omitted when set to 0.

If this constant remains undefined, it defaults to 1, and the function is included in the executable image. To optimize memory footprint, if no osOpen* functions are called within the application, the system automatically ignores object names and excludes the underlying name management logic. This significantly reduces the final size of the output code. For detailed information regarding object naming conventions and opening procedures, refer to the System Objects Management section.
