To specify that you want to use processwide hacking, give the caller and callee module the same name. |
It is an alternative to a 0800 number where the callee bears the full cost of the call. |
The interpreter must provide for correctly resuming the caller when the callee has returned its value. |
Once the callee terminates, it cleans the stack that it has been locally using and pops the next value stored on top of the stack. |
