Expanded names

By using the `\EXPAND` qualifier, you can enter names that must be constructed, or string variables that can be expanded.

For example, suppose that scalar `I` has the value `2`, and the string variable `TXT` has the value `'X2'`.

`DESTROY\EXPAND 'X'//RCHAR(I)` | will destroy `X2`
`DESTROY TXT` | will destroy `TXT`
`DESTROY\EXPAND TXT` | will destroy `X2`
