specifies a character
constant, variable, or expression.
Details
In a DATA step, if the
RIGHT 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 RIGHT function returns
an argument with trailing blanks moved to the start of the value.
The length of the result is the same as the length of the argument.
Example
The following SAS statements
produce these results.
