REVERSE
The REVERSE function returns a character string of exactly the same length as the argument, whose characters are exactly the same as those specified in the argument except that they are in reverse order. For arguments of type national, character positions are reversed.
The function type depends on the type of the argument, as follows:
| Argument type | Function type |
|---|---|
| Alphabetic | Alphanumeric |
| Alphanumeric | Alphanumeric |
| National | National |
- argument-1
- Must be class alphabetic, alphanumeric, or national and must be at least one character in length.
The returned
value is a character string of the
same length as argument-1, with the characters
of argument-1 in reversed order. For example, if argument-1 contains ABC,
the returned value is CBA.
