The Data step in SAS(R) 6.12 is the recipient of 50+ new functions. These new functions are broken into the following groupings data set functions, external file functions, library and catalog functions, special functions, variable functions, and statistical functions. The objective of this ...
From “The Secret Life of DATA STEP” translated by sxlion 图1 DATA步的动作流程图 编译阶段 如上所述,DATA步的第一个阶段就为编译阶段。在编译阶段SAS的任务如下: 自动将SAS语句编译成将会在后面执行的机器语言 确定每个变量的类型和长度 确定变量是否有必要进行类型转换 如果有INPUT语句,为外部文件新建读取...
为了指定字段的格式,我使用data step INFILE来执行导入工作。我想知道是否有任何方法可以读取完整的数据,而忽略非ascii字符。注意:我现在唯一的修复方法是首先导入SAS,得到错误信息并知道错误的确切位置,打开文件(等待大约10分钟),手动定位我找到的位置并删除字符。显然,它很繁琐,很难重复。
1:当output没有规定数据集名字时,把当前观测《也就是一行数据》输出到data步后面的所有数据集的末尾<注意是所有数据集>意味着纵向合并,当规定数据集名字时,把pdv当前观测输出到output规定的数据集末尾。 2:在有output语句和run语句同时存在的data步里面,pdv只会执行output的结果到正在被创建的数据集,而执行run语句的...
