Declare Operator - ( ByRef lhs As T, ByRef rhs As T ) As Integer
Declare Operator - ( ByRef lhs As T, ByRef rhs As Integer ) As T
Declare Operator - ( ByRef lhs As Integer, ByRef rhs As T ) As T
result = lhs - rhs
lhs
Returns the subtraction of two expressions.
When the left and right-hand side expressions are numeric values, Operator - (Subtract) returns the subtraction of the two values.
If either the left or right-hand side expressions is of Pointer type, Operator - (Subtract) performs pointer arithmetic on the address, returning the result.
Neither operand is modified in any way.
This operator can be overloaded to accept user-defined types.
will produce the output:

rhsThe right-hand side expression to subtract.
TAny pointer type.
Return Value
Returns the subtraction of two expressions.
Description
When the left and right-hand side expressions are numeric values, Operator - (Subtract) returns the subtraction of the two values.
If either the left or right-hand side expressions is of Pointer type, Operator - (Subtract) performs pointer arithmetic on the address, returning the result.
Neither operand is modified in any way.
This operator can be overloaded to accept user-defined types.
Example
Dim n As Single
n = 4 - 5
Print n
Sleep
n = 4 - 5
Print n
Sleep
will produce the output:
-1
Dialect Differences
