Any and all Stack or Memory Registers can be viewed by building additional displays into a calculator. Stack and Memory Registers are used to contain alpha or numeric data. So, users can either click on a key with their mouse, or type a character from the keyboard to execute a calculator function. There are 18 significant digits in all calculations. All displays can be stretched to show up to 24 characters.
Users can edit the tape's text by simply clicking on the tape.
Numeric results can be output to the papertape, then subsequently printed out on any printer or saved as a text file. Paper tape justification can be adjusted by a toggle switch while the calculator is running. Standard text files can be opened and edited on the Paper tape. Most HP-41C programs will run, with a few minor exceptions, in CCS calculators. These exceptions are due to differences in hardware.
