preprocessor statement
预处理(程序)语句
In PL/1, a special statement appearing in the source program that specifies how the source program text is to be altered; it is identified by a leading percent sign and is executed as it is encountered by the preprocessor.
(it appears without the percent sign in preprocessor procedures, which are invoked by a preprocessor function reference.)
在PL/1语言中,源程序中出现的一种专用语句,指明源程序文本如何修改。这种 语句用前置一个百分比符号(%)来标识,当预处理程序遇到这种语句时就立即执行。 (这种语句在由预处理函数引用所调用的预处理过程中出现时不带百分号。) |
