The usual array functions in SAS are: Dim dimk hbound Hboundk LBound lboundkThe array function counts the dimensions, the upper and lower bounds of the array, and facilitates the writing of the portable program, which includes:Dim (x) To find the number of elements in the first dimension of the array xDIMK (x) to find the number of elements in the array x K dimensionLBound (x) to find the lower bound of the first dimension of array XHbound (x) to find

SAS and SATA Hard Drive guidelines When you add a hard disk drive to the server, follow these general rules: The system will automatically set all drive numbers If you are using only one hard drive, install the drive in the home with the smallest drive letter. When multiple drives are divided into the same drive array, these drives must have the same capacity to maximize storage space efficiency. Drives in the same logical volume must have the sa

OracleThe decode function in the database is one of the common functions of Oracle PL/SQL. What is its purpose? Next we will introduce this process and how to use it.SAS macroTo implement the decode function in the Oracle database. First, let's construct an example. If we want to add a salary to a staff member of zhixing, the standard is: the salary is less than 8000 RMB plus 20%; the salary is more than 8000 RMB plus 15%, usually, select the salary field value in the record first? Select salary

missing X includes 0 values, applicable to both numeric and numeric values; run; proc print data = B Noobs; The most important differences between where and if 1: Where is not executable, if is executable 2: Where has its own specific expression. If is a general expression, for example, where X is missing; 3: Where can only be selected from the existing SAS data set. If statements can also be selected from observations generated by input statements.
