• Select prgm from the PRGM CTL menu, and then enter the program name. prgmname When prgmname is encountered during execution, the next command that the program executes is the first command in the second program. It returns to the subsequent command in the first program when it encounters either Return or the implied Return at the end of the second program. Program Output Subroutine ( ' 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) Chapter 16: Programming 294
