REVERSE Function

Arguments

argument

specifies a character constant, variable, or expression.

In a DATA step, if the REVERSE function returns a value to a variable that has not previously been assigned a length, then that variable is given the length of the first argument.

The last character in the argument becomes the first character in the result, the next-to-last character in the argument becomes the second character in the result, and so on.

Note:   Trailing blanks in the argument become leading blanks in the result.
