∟\$b-\$a - Using Hard References in Other Operations
This section provides a tutorial example on using hard references as numeric, string or Boolean values in other operations.
A hard reference can also be used as scalar value in other operations:
It will return an integer representing the memory location of the referenced
object, if a number is expected.
This allows you to calculate the memory location difference by subtracting one reference from another reference.
It will return the object type and memory location in hex of the referenced
object, if a string is expected.
It will return TRUE, if a Boolean value is expected.
Here is a tutorial program to help you understand this:
