用use命令使用不了，内存不够，该怎么解决啊。
use 1998_2008panel
op. sys. refuses to provide memory
    Stata's data-storage memory manager has already allocated 1760m bytes and
    it just attempted to allocate another 16m bytes.  The operating system
    said no.  Perhaps you are running another memory-consuming task and the
    command will work later when the task completes.  Perhaps you are on a
    multiuser system that is especially busy and the command will work later
    when activity quiets down.  Perhaps a system administrator has put a limit
    on what you can allocate; see help memory.  Or perhaps that's all the
    memory your computer can allocate to Stata.
下面是错误提示，我该怎么设定内存啊！大神求帮忙啊，导师刚布置的任务。
