这些函数的调用方法类似其它语言，比如求x1，x2，x3三个自变量的和可以用函数SUM(x1,x2,x3) 。另外，SAS还提供了函数调用的另一种语法以便于把多个数据集变量作为函数自变量，其格式为“函数名(OF 变量名列表)”，其中变量名列表可以是任何合法的变量名列表，比如x1 ，x2，]]>https://blog.youkuaiyun.com/gqm1982/article/details/3794423https://blog.youkuaiyun.com/gqm1982/article/details/3794423gqm1982Fri, 16 Jan 2009 11:30:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2479746https://blog.youkuaiyun.com/gqm1982/article/details/2479746gqm1982Sun, 25 May 2008 12:53:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294663https://blog.youkuaiyun.com/gqm1982/article/details/2294663gqm1982Tue, 15 Apr 2008 17:46:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294657https://blog.youkuaiyun.com/gqm1982/article/details/2294657gqm1982Tue, 15 Apr 2008 17:42:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294639https://blog.youkuaiyun.com/gqm1982/article/details/2294639gqm1982Tue, 15 Apr 2008 17:38:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294634https://blog.youkuaiyun.com/gqm1982/article/details/2294634gqm1982Tue, 15 Apr 2008 17:37:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294630https://blog.youkuaiyun.com/gqm1982/article/details/2294630gqm1982Tue, 15 Apr 2008 17:34:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294622https://blog.youkuaiyun.com/gqm1982/article/details/2294622gqm1982Tue, 15 Apr 2008 17:33:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294607https://blog.youkuaiyun.com/gqm1982/article/details/2294607gqm1982Tue, 15 Apr 2008 17:30:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2294580https://blog.youkuaiyun.com/gqm1982/article/details/2294580gqm1982Tue, 15 Apr 2008 17:23:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/2225763https://blog.youkuaiyun.com/gqm1982/article/details/2225763gqm1982Fri, 28 Mar 2008 14:36:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1904612https://blog.youkuaiyun.com/gqm1982/article/details/1904612gqm1982Tue, 27 Nov 2007 18:59:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1843226https://blog.youkuaiyun.com/gqm1982/article/details/1843226gqm1982Thu, 25 Oct 2007 13:55:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1831924https://blog.youkuaiyun.com/gqm1982/article/details/1831924gqm1982Thu, 18 Oct 2007 23:40:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1831923https://blog.youkuaiyun.com/gqm1982/article/details/1831923gqm1982Thu, 18 Oct 2007 23:39:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1831922https://blog.youkuaiyun.com/gqm1982/article/details/1831922gqm1982Thu, 18 Oct 2007 23:38:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1831921https://blog.youkuaiyun.com/gqm1982/article/details/1831921gqm1982Thu, 18 Oct 2007 23:37:00 +0800https://blog.youkuaiyun.com/gqm1982/article/details/1831919https://blog.youkuaiyun.com/gqm1982/article/details/1831919gqm1982Thu, 18 Oct 2007 23:36:00 +0800
