In general, to be THREADSAFE, a routine should not use any global or static data areas.

一般来说，要想定义为THREADSAFE，例程不应该使用任何全局或静态数据区域。

If the procedure is defined as THREADSAFE, the database manager can invoke the procedure in the same process as other routines.

如果过程定义为THREADSAFE，数据库管理器就可以在其他例程的进程中调用这个过程。

youdao

If the procedure is defined as not THREADSAFE, the database manager will never invoke the procedure in the same process as another routine.

如果过程定义为NOT THREADSAFE，数据库管理器就绝不会在其他例程的进程中调用这个过程。
