You can use nested formats as follows to accomplish this task: proc format Dates before July 15, 2005, should be formatted as "Not Open" and dates after December 31, 2006, should be formatted as "Too Late." You want to read dates from July 15, 2005, to December 31, 2006, using the mmddyy10. You can also include the name of a SAS format or user-defined format or informat, rather than a text string in place of a label. So, in this example, missing values and any values beginning with numbers will be labelled as 'Error '. In an alphabetical sort, SAS sorts numeric values before A. All other values (including missing) will be displayed as 'Error '. In the above example Any values which come after A (including A) and before K (not including K), in an alphabetical sort, will be labelled as ‘First 10’.Īny values which come after K (including K) and before U (not including U), in an alphabetical sort, will be labelled as 'Second 10'.Īny values which come after 'U' (including U) will be labelled as 'Remaining'. We could create the following proc format We can also apply the basic principles of ranges to character formats as well.

The code values (on the left of the equals signs) must be quoted.

The name of the format must start with a dollar sign ($).

Value labels can also be applied to character/string data values. Others also include missing values if it is not specified. LOW refers to the least available number, HIGH refers to the highest available number and OTHER includes all numbers not specified. Ranges can include or exclude the bounding values, depending on the use of various keywords like HIGH or LOW proc format For example, we can apply a single ‘label’ to ranges of values with code like this: proc format In addition, we can use ranges and lists of values to create formats. Ranges can be multiple values separated by commas. proc print data=sashelp.pricedata(obs=5) īeyond just a simple one-to-one mapping as illustrated above, we can also map multiple values to a single label. Now, you can apply the RegionFmt in any SAS dataset or Proc steps. proc format Īfter running, the above code, check the log to see if the format is created. The PROC FORMAT to assign region names to values is as below. We would like to assign region names the USA, EUROPE and ASIA corresponding to the values of 1,2 and 3.Īs you can see from the PROC FREQ output, the region column has values of 1,2 and 3. We have taken the example from the SASHELP.PRICEDATA dataset.

The most common way of labelling data is to simply assign each unique code its own label.

Should not end with a period in the VALUE statement Basic Example of PROC FORMAT.

Cannot be the name of an existing SAS format.

For numeric values, the name must have a letter or underscore as the first character.

For character values, the first character must be a dollar sign ($), and a letter or underscore as the second character.
