How do I create a proc format from a dataset?
A very efficient way of defining Formats and Informats is to use an Input Control Data Set with Proc Format, rather than writing VALUE or INVALUE statements. Create the Input Control Data Set with the variables START, LABEL and FMTNAME. Then run a Proc Format step which points to the CNTLIN data set as follows.
How do you create a user defined format in SAS?
This is done using the PROC FORMAT procedure. The general form of PROC FORMAT is: PROC FORMAT; VALUE format-name Data-value-1 = ‘Label 1’ Data-value-2 = ‘Label 2’; VALUE format-name-2 Data-value-3 = ‘Label 3’ Data-value-4 = ‘Label 4’; …..; RUN; The first line is the start of the proc step.
How do you save a format in SAS?
To permanently store a SAS® format so that it can be used in subsequent SAS sessions, you need to use the LIB= option on the PROC FORMAT statement. This option specifies the library, catalog name, or both, that will contain the format catalog.
What is Proc format Cntlin?
ABSTRACT (CNTLIN=) Using the SAS® system and the CNTLIN= option in PROC FORMAT, a format can be defined where all the account numbers you want identified are set to a value of ‘KEEP”.
How do I format a function in SAS?
Using a Function to Format Values
- Use the FCMP procedure to create the function.
- Use the OPTIONS statement to make the function available to SAS by specifying the location of the function in the CMPLIB= system option.
- Use the FORMAT procedure to create a new format.
- Use the new format in your SAS program.
What does format do in SAS?
Informats tell SAS how to read data, while formats tell SAS how to write (or print) data. This tutorial shows how to use informats and formats to correctly read in data, as well as change how printed data is displayed to the user.
Where are formats stored in SAS?
By default, the format catalogue is stored in the work directory and deleted at the end of the SAS session (along with temporary data sets).
What is Cntlin SAS?
The CNTLIN option enables you to create user-defined formats from a SAS data set (input control data set). The CNTLOUT option enables you to create a SAS data set (output control data set) containing format details from an entry in a SAS format catalog.
How do SAS formats work?
All SAS formats are stored in a catalog (collection of formats). When we create a Format, it gets stored in the catalog. If we don’t specify the catalog, then SAS stores formats in the WORK library in a catalog called FORMATS. Like other datasets of WORK library, they also get deleted at the end of the session.
