The maximum length of a system object's name string is determined by the OS_SYS_OBJECT_MAX_NAME_LEN constant. If this value is set to 0, integer values of the INDEX type are used as identifiers instead of strings. Names must always be passed to system functions using a variable of the SYSNAME type. This type is configuration-dependent and is automatically mapped to either the PSTR or INDEX type. By default, this constant is set to 8.
