+; Example 6 - Variable Pointers
+; ---------------------------------------------------------------------------- ;
+; Variable Pointers, the one thing we have all waited for in addition to every-
+;  thing else. Now we can pass things by reference instead of copying to & from
+;  a bank. Unfortunately it only works for Integers, Floats and Types.
+
+; For Integers, all you have to do is declare a variable and then call the func-
+;  tion that retrieves the pointer:
+Global MyVariable% = 1
+Global MyVariablePtr% = 0
+MyVariablePtr = BP_GetVariablePointerInt(MyVariable)
+
+; Same for Floats, slightly different function though
+Global MyVariable2# = 1.2
+Global MyVariable2Ptr% = 0
+MyVariable2Ptr = BP_GetVariablePointerFloat(MyVariable2)
+
+; Now we can directly modify them in memory, which means that we can modify them
+;  from anywhere - inside and outside our program. What you do with this is up
+;  to your imagination, just don't fuck up. Computers don't like that.
+
+; Usage Example
+Print MyVariable
+PokeMemoryInt(MyVariable, 283)
+Print MyVariable
