Unofficial Name: OffPageJump
BCALL Address: 44F2
Jumps to a specified address on a specified page.
- Push pointer to table entry before calling
Push the address of a B_CALL table entry before B_JUMPing to this entry point. Such an entry looks like this:
.DW wAddress .DB bPage
Do not B_CALL this entry point, only B_JUMP. Unlike other B_JUMPs, however, this one does return. It could have uses for multipage applications, I guess. Push a return address before the below code if you want to regain control. TI-Navigator uses it like this.
Jump to ClrLCDFull and end execution (on OS 1.12 from a RAM program):
ld hl,dataPtr push hl B_JUMP OffPageJump dataPtr: .dw 5A71h ;these are specific to OS 1.12 .db 01h
