### How do you use length in SAS?

The LENGTH function returns the length of a character string in characters, excluding trailing blanks, whereas the LENGTHM function returns the amount of memory in bytes that is allocated for a character string. LENGTH always returns a value that is less than or equal to the value returned by LENGTHM.

#### What is SAS length?

In SAS, the length of a variable is the number of bytes SAS allocates for storing the variable. It is not necessarily the same as the number of characters in the variable. By default, SAS uses 8 bytes to store numeric variables. Variables containing integer values can be stored using less than 8 bytes.
