== Synopsis ==
'''Unofficial Name:''' OffPageJump

'''BCALL Address:''' 44F2

Jumps to a specified address on a specified page.

=== Inputs ===
* Push pointer to table entry before calling

=== Outputs ===
* None

=== Destroys ===
* Unknown

== Comments ==
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.

== Example ==
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
