The ID variable, which can be character or numeric, identifies observations on the output when you specify the LIST option. The VAR statement lists the numeric variables to be used in the cluster analysis. If you omit the VAR statement, all numeric variables not listed in other statements are used.

Whenever SAS encounters an invalid or blank value in the file being read, the value is defined as missing. In all subsequent processes and output, the value is represented as a period (if the variable is numeric-valued) or is left blank (if the variable is character-valued). In DATA step programming, use a period to refer to missing numeric values.

The input command reads the character variable state from columns 1-2, the numeric variables pop, inc_cp, and spend from columns 12-19, 20-25, and 28-32 from the data set c:\users\states.txt. Variable names followed by a ‘$’ are character variables and those without a ‘$’ are numeric.

In the above example the “1.” following ID tells SAS that the field ID is numeric and has a width of 1. SBP and DBP have widths of 3. The “$1.” is a format telling SAS that SEX is a character variable of width 1. The format specifications in the INPUT statement are called “informats.” Example SAS informats are:

Character input values cannot be longer than 8 bytes unless the variable is given a longer length in an earlier LENGTH, ATTRIB, or INFORMAT statement. Character values cannot contain embedded blanks unless you change the delimiter. Data must be in standard numeric or character format. PROC SORT

Use line holders: double trailing @@ or single trailing @. Double trailing @@: a double trailing at the end of the sas input statement instructs sas to hold that line of data, continuing to read observations until it either runs out of data or reaches an input statement that does not end with a double trailing.

Note that SAS does is not case sensitive; that is, it read “A” and “a” as the same. The second and remaining characters in a variable name can be other letters, numbers, or underscores (i.e., “_”). By default SAS assumes that variables are numeric. If a variable is character, then the name must be followed by a space and then a $.
Introduction to SAS by Example:
Without a $ after a variable name, SAS assumes that the variable is numeric (the default). Length statement: Sometimes it is necessary to include a length statement to allow character variables to be longer than the default length of 8 characters. Character …
