@charactervariable 首先确定字符变量所取值(即字符串)在输入行的位置,然后把指针移到这个字符串之后的第一个非空格列。 @(characterexpression) 先确定字符表达式值的位置,然后移指针到其后第一个非空格列。 @+n 把指针向右移动n列。如: INPUT @20 AGE 2. +4 WEIGHT; @+...
例如:id_num = input ( id,6. );id原本是character variable ,这句代码将id变成numeric variable,变量总长度为6。 INPUTN 和 INPUTC函数 允许在程序运行时指定一个numeric 或 character informats。 如何使用INPUTN 转换 informats ,由inputn函数的另一个参数的值决定。
sas 合并不了,提示错误为:ERROR: Variable ___1 has been defined as both character and numeric. 答案 这是因为你的合并变量在两个来源数据集中定义的类型不一致,一个是字符型,另外一个是数值型.需要重新定义类型,比如说用format语句.相关推荐 1sas 合并不了,提示错误为:ERROR: Variable ___1 has been ...
The new character variable padding (CVP) engine expands character variable lengths, using a specified expansion amount, so that character data truncation does not occur when a file requires transcoding. Character data truncation can occur when the number of bytes for a character in one encoding is ...
