We have applied the SAS system format 6. Note that applying a format does not affect the value of the variable. BMI will still be stored using many significant digits and sex will be stored as an integer between 0 and 9. We can also specify formats in individual proc steps, which override the default format if a default format exists. We could, for example, use the following code, which would produce a listing of the actual values of the variable sex. If we did not assign formats to the variables bmi or sex in a data step, we can assign them is a proc step, in which case the formats are only used within that proc step. For example:. Any calculations made using a variable in a data step will be based on the raw data i. When fitting statistical models, however, the model is fitted to the formatted value. Paul W Dickman.

The DAY. Now when you view the values of variable bdayyou can see that they use a two-digit value for the month, followed by a two-digit day, sas format informat, followed by a four-digit year:. This example associates a character informat and a numeric informat with SAS variables.

You must specify at least one variable when specifying an informat or when including no other arguments. Numeric informats are applied to numeric variables, and character informats are applied to character variables. These default informats apply only to the current DATA step. SAS reads the variables by using the scanning feature of list input, but applies the informat. In modified list input, SAS.
