The SCAN function can also be used to read from right to left. When you specify a negative number in the second argument of the functionnth-word, SAS starts scanning from the right. For example -1 means the last
Countw函数,与scan函数用法相似,以分隔符来数string可以被分为几个部分。 Countc函数,书写格式相同,作用不同,查找charlist中每个字符在string中一共出现的次数,其中v修饰语表示查找charlist之外(包括空格)的字符数量,与t一起使用,则可以忽视尾部空格的数量(中间空格仍然存在被计数)。
When we dig into the problem, we may discover the issue: either a SAS function was utilized incorrectly or the programming logic wasn't applied properly. In this paper, the author will use examples such as SCAN functionand LAG function to demonstrate these points in an effort to share ...

If you use countw() to determine the number of "words" in your string, you must supply the same list of delimiters that you use in the scan() function, or it will give you a higher number of "words" than are present in the string. Depending on your settings, this might produce en...
