Bocfel includes rudimentary support for cheating, by allowing certain areas of memory (represented by their addresses) to be frozen such that they always contain specific values. As a result, you are able to do things such as always having money, never being hungry, and so on.
Addresses are typically represented in hexadecimal. However, the Z-machine has the concept of global variables. Global variables are simply named addresses. For example, the global variable
G00 of a particular game might map to the address
0x1212, and as such, these two addresses are interchangeable. When displaying addresses, the global variable notation is used if an address is a global variable. Otherwise, the address is displayed in hexadecimal.
