MY comment is not specific to the TI-85...




TO allocate a STACK on the Z-80...


Allocate Space for the STACK...
Get and Save the CURRENT STACKPOINTER...
Load the StackPOINTER to the LASTADDRESS+1 of the STACK Allocated...
and when you no longer need the STACK... Load the STACKPINTER with the Saved 
Value..

.|     Can someone explain how to define your own stacks???  I think I have
.|some idea, but I don't quite know.  Do you allocate memory and then
.|allocate a seperate variable to be a stack pointer to manipulate it?
