Section 8
Multiple Programs
You can store multiple programs in program memory, provided that you
separate them by instructions that will halt program execution after each
program is run and return to the beginning of the program. You can run
programs after the first one stored in program memory by setting the calculator
to the first line of the program before pressing ¦.
Storing Another Program
To store a program after another program is already stored in program memory:
1. In Program mode, go to the last line of the last program. Do not clear
program memory.
2. If there is only one program already in program memory, add a t00
instruction so that program execution returns to line 00 after this first
program is run.
3. Key the program into program memory. (Be sure that any t
instructions specify the correct line numbers.)
4. Press ¦. This will halt program execution at the end of the
program.
5. If the new program does not end with a loop, key in a t instruction
to the first line of the new program. This transfers program execution
back to the beginning of the program if ¦ is pressed to rerun the
program.
Example: Assuming that program memory still contains the last program from
the preceding section (which consisted of 13 program lines), store after that
program the temperature conversion program from section 5 (page 56). Since
this will be the second program stored in program memory, we'll insert a
t00 instruction to separate it from the first program (step 2 above). This
program does not end with a loop, so we'll do steps 4 and 5, too.
