Alphanumeric display, storage, and programming.Indirect addressing via any register using the IND modifier.Convenient insertion and deletion of program steps.Conditional and unconditional branching based on register values and flag settings.Flags 0-4 have annunciators in the display. Flags include data entry, printing and program control etc.

Reassignable 'user' keyboard allows one-key access user programs, built-in functions and extensions.Label addressing with strings up to seven characters long.The HP-41C and CX models come with 1000-2000 lines of memory. The basic HP-41C provides 200-400 lines with each module providing 200-400 more. Fully merged keystrokes (multi-keystroke steps require just one line.).Access to the stack and LAST x via STO and RCL commands.The ОЈREG command allows the 6 statistics registers to be positioned anywhere. Registers 00-99 are directly available 'primary registers' while registers 100-318 are indirectly available 'extended registers'. HP-41CV and CX models come with 4 modules built-in providing 319 registers total. 63 storage registers (R00-62) with memory modules that add an additional 64 storage registers each.A storage register converts to about 3-6 lines of program memory. The same memory can be defined for use by programs or data via the SIZE command which takes the number of storage registers as a parameter. Continuous memory with automatic shut-off after 10 minutes of inactivity.Using the Optional HP 82104A Card Reader.
