Which of the following FORMAT procedures is correctly written?

  1. proc format lib=formtlib value colorfmt; 1='Red' 2='Green' 3='Blue' run;

  2. proc format lib=formtlib; value colorfmt 1='Red' 2='Green' 3='Blue'; run;

  3. proc format lib=formtlib; value colorfmt; 1='Red' 2='Green' 3='Blue' run;

  4. proc format lib=formtlib; value colorfmt 1='Red'; 2='Green'; 3='Blue'; run;

The correct answer is: proc format lib=formtlib; value colorfmt 1='Red' 2='Green' 3='Blue'; run;

The correct choice effectively demonstrates proper syntax for creating a custom format within the SAS programming environment. In SAS, the PROC FORMAT procedure is used to define custom formats that can then be applied to variables within datasets. In this choice, the syntax begins with the PROC FORMAT statement, indicating the start of a format definition. The inclusion of 'lib=formtlib' specifies that the format will be stored in a library named 'formtlib', which helps keep formats organized and accessible for future use. The 'value colorfmt' portion clearly identifies the name of the format being created, and the subsequent lines correctly define the format values with their corresponding labels. Each value is assigned a label, where '1' is associated with 'Red', '2' with 'Green', and '3' with 'Blue', following the structure that SAS expects. This specific format definition adheres to SAS's syntax rules, ensuring that the format can be executed without errors. Properly closed with a 'run;' statement, it indicates the end of this block of code, instructing SAS to execute all preceding formatting instructions. By following these conventions, the answer firmly demonstrates how to create a user-defined format for effective data representation in SAS.
