How can the SPLIT= option be used in SAS?

The SPLIT= option in SAS is utilized to control line breaks in column headings. When creating reports and output tables, particularly in procedures like PROC PRINT or PROC REPORT, the column headers can become lengthy and may need to be formatted for better readability. By specifying the SPLIT= option, you can indicate a character that will act as a split point in the column name, allowing the title to break into multiple lines in the displayed output. This is particularly helpful in improving the visual appeal and clarity of reports where column headers are too wide to fit neatly on one line.

The other options do not align with the functionality of the SPLIT= option. The option is not used to specify the maximum number of variables, retain missing values, or limit the number of observations displayed. Instead, it specifically enhances the formatting of output by managing how headings appear, making it easier for users to interpret the data.
