Notes about Calling Programs
Variables are global.
label used with Goto and Lbl is local to the program where it is located. label in one program is not
recognized by another program. You cannot use
Goto to branch to a label in another program.
Return exits a subroutine and returns to the calling program, even if it is encountered within nested
loops.
Running an Assembly Language Program
You can run programs written for the TI-84 Plus in assembly language. Typically, assembly
language programs run much faster and provide greater control than the keystroke programs that
you write with the built-in program editor.
Note: Because an assembly language program has greater control over the calculator, if your
assembly language program has error(s), it may cause your calculator to reset and lose all data,
programs, and applications stored in memory.
When you download an assembly language program, it is stored among the other programs as a
PRGM menu item. You can:
• Transmit it using the TI-84 Plus communication link (Chapter 19).
• Delete it using the MEM MGMT DEL screen (Chapter 18).
To run an assembly Program, the syntax is:
Asm(assemblyprgmname)
