Macro variables are just a text substitution mechanism. When you execute SAS code, the value of the macro variable (a text string) is substituted into SAS code (where the macro variable was in the code), and this substitution of macro variable value into the code MUST produce valid working ...
In SAS, find function which helps to find the input strings for the first position and occurrence of the specified substring. It will return the substring position that cannot be found on the character string, substring, modifier, or start-position of the strings with optional arguments on the ...
这里的separator是分隔符,string1、string2等是要合并的字符串,result是合并后的结果。例如,如果要将字符串"Hello"和"World"合并成"Hello-World",可以使用以下代码: 推荐的腾讯云相关产品:腾讯云云函数(SCF),它是一种事件驱动的无服务器计算服务,可以用于处理SAS子串合并等数据处理任务。详细介绍请参考腾讯云云函数官...

In the following example of SAS code, the argument string has a value of 'summer', and the argument position has a value of 4:x=char('summer', 4); In the following example, string and substring are required arguments, while modifiers and startpos are optional. FIND(string, substring <,...

FIND Function Searches for a specific substring of characters within a character string. FINDC Function Searches a string for any character in a list of characters. FINDW Function Returns the character position of a word in a string, or returns the number of the word in a string. FIRST...
characters in the stringafter the comma and searches for the first instance of any of them,thus when it encounters the lower case “a,” at the third character,it returns that index. (If these were all uppercase, it wouldreturn a 1).This is useful if you need to find any...
you are taking the substring. Finally, the variable REP is created by using the REPEAT function. As you will find out later in this chapter, the REPEAT function takes a string and repeats it as many times as directed by the second argument to the function. Using the same logic as the ...
