第七类,其他函数  以下是其他函数的不完全情况:

1,有模块有自己的专用函数,如IML模块里面的函数。

2,现在模块中出现,如果用得很多的话,就变成了常规函数,如有些函数是从其他版本中其他模块转过来的,如SAS/ETS的INTCINDEX,INTCYCLE等等; SAS High-Performance Forecasting的HOLIDAY和NWKDOM函数等等就是这样。

3,还有一类函数是SAS文档中没有记录的,比如说PROC SQL语句中的 MONOTONIC( ) 函数,但是可以使用的,半官方的解释就是不成熟,处于试用中的函数,这种函数有些地方确实能起到惊艳的作用,但需要小心使用,多测试,防止意外发生。

4,有些函数文档里一些情况也没叙述完全,可能在调试中。比如说函数indexw(),具体见说明见mysas圈

22 11月 10 最全的SAS9.2函数列表一


SAS提供了大量的内置函数,并且在数量和内容上不断的发展改进,从版本9.2开始还提供了自定义函数功能。使用合适的函数,将会使你的工作效率加倍。2008年我在SASor论坛上贴了一个SAS9.2新增函数的列表,具体见论坛帖子;2009年我曾经在技术博客上对SAS函数做了比较深入的讨论,对SAS函数从版本6到版本9.2进行了细致的综述,详见SAS函数&CALL例程介绍与实例精选,并在SAS爱好者上海聚会分享了这一内容,当时的PPT见“SAS函数和CALL 例程的发展”。

当时所关注的函数其实仅仅集中于SAS常规函数,尽管如此,SAS9.2 的常规函数已达到499个。庞大的函数库确实给SASor们带来了非常多的方便,但是仓库式的SAS builted in帮助太杂乱,常常让人有一种“不识庐山真面目,只缘身在此山中”的感觉。有时,需要的函数找不到,找到的函数又不合适。其实SAS很体贴地不断增加高效的函数来精简你的代码和提高编程速度,可惜很多函数,SASor们并不知晓,常常看到别人使用的时候,才惊叹“原来SAS已经提供了这样的函数,我编了半天小算法”,或者“白费这么大劲,编了个宏”等等。这里按类列出SAS9.2版本的函数,供大家参考。

按不同的使用环境,SAS一共有七大类函数:

一,常规函数 ;二,windows环境下函数;三,OpenVMS虚拟内存环境下函数;四,z/OS操作环境下函数,五,宏语言函数;六,多国语言函数,七,其他函数

第一类函数常规函数最常用,数量也最多,这里依次列出所有的常规函数。
