SAS数据清理与分析技术指南说明书
The COMPARE function identifies the location atwhich two character strings differ. This information can be used in combination with the SUBSTR function to parseand compare text strings, accounting for mistakes between two values. The paper will also touch on ways to cleanand organize character data ...
Thats becaue when I convert the character to numeric for comparasion purpose, the values wiht more than 8 characters are trimmed and so wrong matching ouptut is generate. Is there any way I can compare this two variable. Note : Size of both vairbles are $9 and $32 and the values in ...
CAT() plus TRIM(), LEFT() and a separater delimiter between the variables - v9func = CATX(‘-’, a, b); COMPARE() Compares two character variables, 0 if no difference COUNT() Counts occurance of text within a character variable SYMPUTX() SYMPUT() plus TRIM(), LEFT() and PUT...

COMPARE returns the position of the left-most character by which two strings differ, or returns 0 if there is no difference. COMPGED compares two strings by computing the generalized edit distance. COMPLEV compares two strings by computing the Levenshtein edit distance. COUNT counts the number of...

关键词_character_表示所有的字会型变量,其它的_numeric_和_all_已经讲解过。Drop和keep选项可以剔除或保留选择的变量。 2.1.2 观测了变量的值的情况后,我们就可能会发现一些错误值,这时可以将这些异常值输出出来(输出到日志中,或输出到数据集中,或外部文件)...
Variable formats are handled by PROC COMPARE as it is used for comparing unformatted values. 22. What is the use of $BASE64X? By using $BASE64X encoding, the character data is converted into ASCII text. 23. What are the features of the SAS system?
