With formatted input, an informat follows the variable name in the INPUT statement. The informat gives the data type and the field width of an input value. Informats also allow you to read data that are stored in nonstandard form, such as packed decimal, or numbers that contain special characters such as commas.

Each variable value is read by using one of these input styles. An INPUT statement can contain any or all of the available input styles, depending on the arrangement of data values in the input records. However, once named input is used in an INPUT statement, you cannot use another input style.

This is handy for small data sets that are. entered by hand, especially for test purposes. This arrangement of data is often called list input.. The rule here is that you. must specify all the variables in the data lines and all the data values must be separated by one or more spaces. You must. also indicate which variables are to be read as character data.

Notice that you need to list the variable names on the INPUT statement and to place a dollar sign ($) after any variable that is. to hold character values. Also notice that the second line of data which has multiple spaces between each data value causes. no problems at all.

The answer: The input variable is the independent variable. In this case the input variable is the number of credit hours John will take. The output variable is the dependent variable. In this case it is the cost of the tuition.

EXAMPLE: Johns pays tuition based on the number of credit hours he takes along with a $25 fixed fitness center fee. John will be taking at least one credit this semester. What is the input variable and output variable.

If numeric-variable is not an integer, SAS truncates the decimal value and only uses the integer value. If numeric-variable is zero or negative, the pointer moves to column 1. Example: The value of the variable A moves the pointer to column 15: a=15; input @a name $10.;

If numeric-variable is negative, the pointer moves backward. If the current column position becomes less than 1, the pointer moves to column 1. If the value is zero, the pointer does not move. If the value is greater than the length of the input buffer, the pointer moves to column 1 of the next record.
