cursors

You can move the cursor by using the mouse.

你可以使用鼠移动光。

For example, in precompiler application development, a cursor is a named resource available to a program and can be used specifically to parse SQL statements embedded within the application.

例如，在开发一个预编译的应用程时，游可以看作供程使用的已命名的资源，它被嵌入程析SQL语句。
