SPSS has 2 variable types: Numeric variables contain only numbers and are suitable for numeric calculations such as addition and multiplication. String variables may contain letters, numbers and other characters. You can't do calculations on string variables -even if they contain only numbers.

So when we want to convert variables in SAS, we are really talking about converting a variable value and assigning it to a new variable. In this post, I will focus on converting a character variable to numeric. First, I show a common pitfall that many SAS users resolve to. 2016-01-06 · SAS will keep evaluating the if-then-else-if statements until it encounters the first true statement.

If you define a numeric variable and assign the result of a character expression to it, SAS tries to convert the character result of the expression to a numeric value and to execute the statement. If the conversion is not possible, SAS prints a note to the log, assigns the numeric variable a value of missing, and sets the These are some of the most common ways that you can create variables in a DATA step: use an In SAS, there are two types of variables: numeric and character. Numeric variables are variables that store numbers. Typically, these are variables that you’ll want to perform arithmetic calculations on, like addition and subtraction.

SAS keywords are not case sensitive. Every SAS program must end with a RUN statement.

SAS When creating variables, do not use the names of special SAS automatic variables (for example, _N_ and _ERROR_) or special variable list names (for example, _CHARACTER_, _NUMERIC_, and _ALL_). When entering data manually, it’s important to identify character values so SAS knows to input the data as a string variable.

If the conversion is not possible, SAS prints a note to the log, assigns the numeric variable a value of missing, and sets the automatic variable _ERROR_ to 1. If you define a character variable and assign the result of a numeric expression to it, SAS tries to convert the numeric result of the expression to a character value. 2015-05-01 · INPUT () can create character or numeric variables based on the informat The source format must match the source variable type in PUT () The source variable type for INPUT () must always be character variables The following examples show how to use these rules to convert from character/numeric or numeric/character: 2018-05-29 · SAS statements that accept variable lists include the KEEP and DROP statements, the ARRAY statement, and the OF operator for comma-separated arguments to some functions.

ARRAY is a SAS keyword that specifies that an array is being defined arrayname a valid SAS name that is not a variable name in the data set. [$] used to specify if the elements in the array are character variables, the default type is numeric [length] used to define the length of new variables being created in the array,

This is the default variable type.

Consider, SAS Array example, a savings data set (savings) that contains 24 monthly variables for a single year, 12 variables for income(Inc1–Inc12), and 12 variables for expenses (Exp1 – Exp12). SAS day-of-the-week and length-of-time calculations are accurate in the future to A.D. 19,900. Various SAS language elements handle SAS date values: functions, formats and informats.
