After merging Employee and Sales, what is the format for the variable Name in the data set Both if LENGTH for Name was defined in earlier data sets?

When merging two datasets in SAS, the result will retain the attributes of the variables from the data sets being merged. The length and format of a variable in the resulting dataset will depend on the attributes defined for that variable in the individual datasets.

In this case, if the variable Name has a defined length in the earlier datasets, the LENGTH statement provides the maximum number of characters that can be stored in that variable. The format $CHARn. specifies a character format that can accommodate up to n characters, meaning it will reflect the maximum character length defined previously.

Given that the answer provided is $CHAR15., this suggests that the length of the Name variable in the concatenated dataset 'Both' is appropriately defined to handle character entries with a maximum of 15 characters. This allows for consistency in how data is stored and prevents truncation or loss of information when merging.

Thus, using $CHAR15. as the format ensures that the merged dataset has accommodated the defined length for the Name variable, which means it can hold all intended character data without loss.
