37 | * This is the information we get after the initial trap that px does. | |
38 | * By passing the "-d" flag, we cause px to call a procedure with the | |
39 | * the following information: | |
40 | * | |
41 | * address of the display | |
42 | * address of the display pointer | |
43 | * address of the beginning of the object code | |
44 | * | |
24ba2374 KM |
45 | * the address of the program counter used in the interpreter procedure |
46 | * (px actually keeps the pc in a register if it can, but stores | |
47 | * it in this location each time around the interpreter loop.) | |
48 | * the address of the main interpreter loop (past the store of pc) | |
