2.3.16.2. - Indirection Operator
The
@ character is a special unary operator that provides indirection
when used in front of a symbol name.
The behavior is similar to the C language
* indirection operator.
In spec, the
@ operator allows reference to a variable whose name
is the string value of another variable.
For example:
1.FOURC> a = "b"; b = PI; print a, @a
b 3.14159 2.FOURC>
