The m and W (memory status) functions are described in detail in
appendix C.
Keep in mind that an error message will result (given the above memory
configuration) if
1. You try to address a register higher than R
the highest register allocated to data storage (
2. You have 322 occupied program bytes and try to load more program
lines (
Error 4
3. You try to run an advanced function with insufficient available

End. Not every program needs to end with a n or ¦ instruction. If
you are at the end of occupied program memory, there is an automatic
n instruction, so you do not need to enter one. This can save you one
line of memory. On the other hand, a program can ―end‖ by simply
transferring execution to another routine using t (section 7).
Labels. Labels in a program (or subroutine) are markers telling the
calculator where to begin execution. Following an ´ label or G label
instruction, the calculator will search downward in program memory for the
