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 word of the string. Since we wish to find the second last word in the ...
scan函数: scan(s,n,"char")表示从字串string中以char为分隔符提取第n个字串。功能(function)：从字符表达式s中搜取给定的n个单词 语法(syntax)1、scan(s,n) n为正数时，从字符s末尾提取n个字符 2、scan(s,n) n为负数时，从字符s开始提取n个字符 3、scan(s,n<,list-of-delimiters>)如果...
SAS: scan函数的修饰语(modifier)说明,另外类比compress function;countw function和countc函数与scan函数的用法比较 SCAN(string, count <, character-list <, modifier>>) count为负,从右往左数。或者使用b修饰语,将从右向左; character-list,默认如果超过一个字符,则每个字符都是一个分隔符。如果使用“K”修...
SAS里INDEX，INDEXC和SCAN的区别为：搜索的内容不同、返回的位置值不同、搜索字符不同。一、搜索的内容不同 1、INDEX：INDEX是搜索一个字符串中，某个字符或某个字符串的位置，找不到时返回0。2、INDEXC：INDEXC是搜索一个字符串中，某个字符或字符串的位置，找不到时返回0。3、SCAN：SCAN是搜索...
Re: Multicharacter string in Scan function Posted 10-23-2017 05:12 AM (5660 views) | In reply to catisgar A very clever solution to this kind of problem (multi-byte delimiters) can be found here: https://communities.sas.com/t5/Base-SAS-Programming/Handling-multi-character-word-delimit...
memscan returns a pointer to the first character in the memory block whose table entry is nonzero, or NULL if all characters have 0 entries in the table. IMPLEMENTATIONmemscan is implemented as a built-in function and uses the TRT instruction to search for a character with a nonzero entry...
