A: Actually, it does on page 18. After pressing MODE + 2 (SD), type a number, then press M+ (the DT key). Repeat. To delete an entry, type the number and press SHIFT + M+ . This is critical for statistics.

Contrary to popular belief, SHIFT + CLR + 1 (Setup) only resets display settings—not programs. SHIFT + CLR + 2 (Memory) clears variables but keeps programs. Only SHIFT + CLR + 3 wipes everything. The manual labels this clearly, but many skip it.
