●CHARACTER:输入的字符或字符串。 ●TIMES:自然数。 此函数的功能是把CHARACTER字符或字符串重复TIMES次。 【例3.16】REPEAT函数应用,对【例3.7】改造,通过repeat返回5个9,实现对缺失值赋值的应用,函数自动生成重复值。 【程序解读】 这个程序实现了【例3.7】中同样的结果,通过REPEAT函数生成5个9对缺失值赋常值。
ANYFIRST Function Searches a character string for a character that is valid as the first character in a SAS variable name under VALIDVARNAME=V7, and returns the first position at which that character is found. ANYGRAPH Function Searches a character string for a graphical character, and returns ...
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 legal SAS code.
