Why add a label to a SAS variable?
Adding a label to a SAS variable is an interesting way to make dataset look easier and interpret it easily. A label provides extra information. For example, consider a student data where we have taken student’s birth date as one variable and student’s date of enrollment as the second variable.

When a label assigns in a proc step, it is temporary; it will only associate with that variable during the execution of the proc step it contains within. (That is, the label will only appear in the output of the procedure it includes in.) When a label assigns in a data step, it becomes a permanent part of the dataset.

A SAS operator is a symbol that represents a comparison, arithmetic calculation, or logical operation; a SAS function; or grouping parentheses. SAS uses two major types of operators: prefix operators. infix operators.
How to compare a prefix in SAS?
You can compare only a specified prefix of a character expression by using a colon (:) after the comparison operator. SAS truncates the longer value to the length of the shorter value during the comparison. In the following example, the colon modifier after the equal sign tells SAS to look at only the first character of values of the variable LASTNAME and to select the observations with names beginning with the letter S :
What is plus and minus in SAS?
When used to perform arithmetic operations, the plus and minus signs are infix operators. SAS also provides several other operators that are used only with certain SAS statements. The WHERE statement uses a special group of SAS operators, valid only when used with WHERE expressions.
What is the value of the expression in SAS?
SAS makes numeric comparisons that are based on values. In the expression A<=B, if A has the value 4 and B has the value 3, then A<=B has the value 0, or false. If A is 5 and B is 9, then the expression has the value 1, or true. If A and B each have the value 47, then the expression is true and has the value 1.
How to use shorthand notation?
You can use a shorthand notation to specify a range of sequential integers to search. The range is specified by using the syntax M:N as a value in the list to search, where M is the lower bound and N is the upper bound. M and N must be integers, and M, N, and all the integers between M and N are included in the range. For example, the following statements are equivalent.

What is format in SAS?
Formats present a value, recognized by SAS, such as a time or date value, as a calendar date or clock time in a variety of lengths and notations. Informats read notations or a value, such as a clock time or a calendar date, which might be in a variety of lengths, and then convert the data to a SAS date, time, or datetime value.
What is SAS date?
SAS can perform calculations on dates ranging from A.D. 1582 to A.D. 19,900. Dates before January 1, 1960, are negative numbers; dates after are positive numbers. SAS date values account for all leap year days, including the leap year day in the year 2000.
What is datetime value in SAS?
SAS datetime value. is a value representing the number of seconds between January 1, 1960 and an hour/minute/second within a specified date. The following figure shows some dates written in calendar form and as SAS date values.
What is the datetime format?
DATETIME formats count the number of seconds since January 1, 1960, so for datetimes that are greater than 02JAN1960:00:00:01 (inte ger of 86401), the datetime value will always be greater than the time value.
What is the year 2000 in SAS?
SAS software treats the year 2000 like any other leap year. If you use two-digit year numbers for dates, you'll probably need to adjust the default setting for the YEARCUTOFF= option to work with date ranges for your data, or switch to four-digit years. The following program changes the YEARCUTOFF= value to 1950. This change means that all two digit dates are now assumed to fall in the 100-year span from 1950 to 2049.
How to read two digit years in SAS?
SAS software can read two-digit or four-digit year values. If SAS encounters a two-digit year, the YEARCUTOFF= option can be used to specify which century within a 100- year span the two-digit year should be attributed to. For example, YEARCUTOFF=1950 means that two-digit years 50 through 99 correspond to 1950 through 1999, while two-digit years 00 through 49 correspond to 2000 through 2049. Note that while the default value of the YEARCUTOFF= option in SAS 9 is 1920, you can adjust the YEARCUTOFF= value in a DATA step to accommodate the range of date values you are working with at the moment. To correctly handle 2-digit years representing dates between 2000 and 2099, you should specify an appropriate YEARCUTOFF= value between 1901 and 2000. For more information, see the YEARCUTOFF= System Option in SAS Language Reference: Dictionary.
