Registers numbered 100 and onwards can only be accessed using indirect addressing. If SIZE has been used to define more than 100 storage registers then RCL nn ReCaLls the data from storage register nn into the stack. STO nn STOres the contents of the X register into the storage register with the given number. Storage can be achieved in the storage registers, of which there are 25 Likely to be lost when a new calculation is started. The four registers that make up the stack are known as X,Y,Z,T.Īuxiliary register LASTx holds contents of X register used in most recent numeric function.Įach of these registers can contain data of any type.īecause of the ephemeral nature of the stack, data in its registers is It stores and shows you intermediate results as you work through a The stack is the scratchpad that you use for performing calculations. Should you need to use more than one functionįrom a Function menu, you can instruct the DM42 to keep the menu open Used one of the functions that it contains, with the exception of the CUSTOM Unlike application menus, a Function menu closes as soon as you have

PROB Combinatorics and probability functions.CONVERT Angle, time, and coordinate conversion functions.CLEAR Functions for clearing programs and variables.Within the application and when you've finished with it, it will close However, you can still open a function menu from When you enter an application and its menu opens, any other menus areĬlosed automatically. There are five applications built into the DM42: If there are more than six functions in the menu then the ▼▲ annunciator is displayed and the ▼ and ▲ keys allow you to scroll through the menu's pages. So most of them are available in menus rather than directly on keys.Įach menu displays a row of labels at the bottom of the screen, one aboveĪ function within the menu is activated by pressing the key directly below it. A 123 represents a soft button or anything on the LCDĭM42 calculator has far too many functions to assign a key to each one,.Press F3 to open help file selection dialog.(c) 2019-2022 SwissMicros GmbH, inspired by the HP-42S Quick Reference Guide (c) Copyright 1988 Dex Smith.Quick Reference Guide DM42 Quick Reference Guide
