说明hash表已经在内存中准备好了。 其中, call missing(key,variable_1) 避免log中出现数据未初始化的提醒。 5. 定义hash对象的 步骤: length d $20;length k $20;if_N_=1thendo;declare hashh();rc=h.defineKey('k');rc=h.defineData('d');rc=h.defineDone();end; 因为: 在 hash object 中 ...

@charactervariable 首先确定字符变量所取值(即字符串)在输入行的位置,然后把指针移到这个字符串之后的第一个非空格列。 @(characterexpression) 先确定字符表达式值的位置,然后移指针到其后第一个非空格列。 @+n 把指针向右移动n列。如: INPUT @20 AGE 2. +4 WEIGHT; @+...
CALL MISSING Routine Assigns missing values to the specified character or numeric variables. CALL SCAN Routine Returns the position and length of the nth word from a character string. CAT Function Does not remove leading or trailing blanks, and returns a concatenated character string. CATQ Fun...

17. What do you understand by CALL MISSING Routine? The character or numeric variables that are specified can be assigned missing values through the CALL MISSING routine. 18. Explain the COMPRESS= Data set option. It is used for compressing the data into new output. ...
所有的CALL Routines必须用 CALL 语句调用。 格式如: CALL routine-name(argument-1< , ... argument-n >) 例如: call set(dsid); 二. 目录 SAS Functions and CALL Routines by Category Arithmetic: returns the result of a division that handles special missing values for ODS output. 对ODS output处...
