HP-41 Help System ROM
HP-41 Help System

Tired of pulling the manual to check (again!) on those pesky system flags? How about the X-Mem file types, Buffer allocations or ASCII Editor hotkeys? Still wishing there was an on-line QRG for the Auto-Complete and universal XEQ modes at your fingertips? And how about starting to use the Formula Evaluation expressions for everyday calculations?

If you responded affirmatively to any (or many) of those questions, you’ll be glad to know that Help is on the way!

The new HP41 HelpSystem ROM is here to assist. Nothing fancy but a basic reference on the topics listed below. The ROM includes four Main programs and 10 Help files that cover frequently asked topics, both standard and advanced. Requires 388 X-Mem registers with all files loaded on-line – but can be accessed individually.

1. HP-41 Flags – Brief description of all 56 flags. Uses 79 X-Mem regs

2. HELP – includes:
a. WARP_Core XEQ+ Hotkeys. Uses 33 X-Mem regs
b. Formula Evaluation Syntax Cheat sheet. Uses 55 X-Mem regs
c. Sub-Function Launchers across the board. Uses 42 X-Mem regs

3. HELP-2, includes:
a. Buffers Allocation. Uses 36 X-Mem regs
b. X-Mem File System. Uses 35 X-Mem regs
c. System Catalogs. Uses 40 X-Mem regs

4. HELP-3 includes:
a. ASCII Editor. Uses 25 X-Mem regs
b. HEX Editor. Uses 25 X-Mem regs
c. Others (MFN, MSG). Uses 38 X-Mem rags


Each entry waits for a short pause on the LCD. This enumeration can be halted by pressing the SHIFT key, resuming again when you release it (not MCODE but a nice application of GETKEYX).

Happy Help Day!

PS. Yes this comes almost 41 years after the system introduction… let’s hope it was worth the wait ;-)
