最后，对操作的调用过程可能不太简单。
调用过程时参数的数量不正确。

在这种方式下，你可以隐藏实现信息，并简化服务的整个调用过程。
In this way, you hide the implementation details and simplify the whole process to invoke the service.
调用存储过程的应用程序将在调用过程之前建立这个连接。
The application invoking the stored procedure will establish the connection prior to invoking the procedure.
有许多种在紧凑循环(tight loop)中调用过程的情况。
There are many cases when procedures are called in tight loops.

如果在调用过程后发出rollback语句，则不会更新策略设置。
If you issue a ROLLBACK after invoking these procedures, policy Settings will not be updated.
这个JCL将调用过程ITSOCB，而它也是生成得到的。
This JCL will invoke the proc ITSOCB, which is also generated.
当包含这些代码片段的应用程序运行时，ARM就会执行这些调用过程。
When the application with the code snippets is executed, the ARM implementation processes these calls.
调用过程时，在过程名后面加上用括号括起来的参数列表。
When you call a procedure, you follow the procedure name with an argument list in parentheses.
注意在函数中我们是如何通过向前传递程序来保持函数调用过程中的状态的。
Notice in this function how we maintained state through function calls by passing the program forward.
这个JCL将调用过程ITSOCBDR，而它也是生成得到的。
This JCL will invoke the proc ITSOCBDR, which is also generated.
请求的操作只准登录过程使用。该调用过程并未被记录为登录过程。
The requested action is restricted for use by logon processes only. The calling process has not registered as a logon process.
而SOAP用XML将消息编码，因此在调用过程的任何一步都极易处理消息。
Because SOAP USES XML to encode messages, it's very easy to process messages at every step of the invocation process.
当然，调用过程之间，对象保存在Twisted服务器的地址空间中。
Between calls, of course, the object is maintained in the address space of the Twisted server.
同时介绍了面向连接和无连接协议两种套接字在程序中的典型调用过程。
Moreover introduces the typical calling process in a program of the facing to connect and none connect protocol sockets.
在调用过程时，您提供的各个实参分别对应于过程中定义的一个形参。
When you call a procedure, each argument you supply corresponds to one of the parameters defined in the procedure.
每次错误处理程序将控制返回给调用过程时，那个过程就成为当前过程。
Each time the error handler passes control back to a calling procedure, that procedure becomes the current procedure.
如果出现临时系统错误、网络故障或服务不可用，准备调用过程中使用的数据将丢失。
If temporary system errors, network failures, or service unavailability occur, the data used in preparation of the call is lost.
如前所述，匿名块的最常见用法就是调用过程语言对象，通常是为了进行测试。
As mentioned, one of the most common USES of anonymous blocks is to invoke procedural language objects, typically for testing purposes.
对处理程序的搜索一直持续到“调用堆栈”，它是应用程序内被调用过程的序列。
The search for a handler continues up the call stack, which is the series of procedures called within the application.
可以在代码中的许多不同位置调用过程，因此可以将过程用作应用程序的生成块。
You can call a procedure from many different places in your code, so you can use procedures as building blocks for your application.
