I feel stupid, but trying to access the CAS section in the iPhone version I only get "NONEXISTANT" as a result when I try "XQT CAS". I have entered "CASFILE" in the alpha register and loaded the MATH module in port 1. What do I do wrong?

You might have better luck asking your question on the developer web site:

AL Software has released a nice application. One has the power of both the HP 41 CX and Reduce at one's finger tips. I have started to work with the two and find that the combination has awesome possibilities.

I first "tasted" RPN with an HP15C and migrated to an HP28S during my university years. This last calculator had features like 32 K of memory, unit conversation, solver, matrices, alphanumeric, list, vectors, etc.. I had loyal services from this beastie well over 20 years. I was disappointed when the clamshell cabling gave way. I found an HP15C emulator for a PDA which was had it merits but the HP41C is yet on another level.

I am just a humble Chemical Engineer with some very basic calculations needs. Quantum Physics or circuit design are not high in my priority list. However it is refreshing to have the possibility to make a quick calculation without the need to turn-on the computer which takes ages to start compared to something like a smartphone. Spreadsheets have also taken some of the edge from handheld calculator but nothing beats a quick and simple result from a ""mini-computer" which, by the way, can also be used as a telephone.

I claim to be still discovering the power of both the 41CX+ and Reduce; nevertheless, I would like to share some of the programs developed to solve some simple tasks. When I have more free time I should look at Warren Furlow's compilation of HP manuals. Thanks to him, our world technical heritage is still alive.

It would be a pleasure to exchange experiences with other users of the 41CX+

Please find below solutions for the following:

• I have tried to be as frugal as possible with the code. I configured the emulator to have 99 storage registers while the rest of the memory is left for programs.

• Revised version of DOCAS to handle hard coded output/input files within calling programs. It can also be used directly as the original version of DOCAS code but the user has the choice of output and input file. Try keeping these to 6 characters to allow them to be stored in a single register.

• The user interface is in 41CX+ and "complex" calculations are made in CAS.

• Bernoulli's equation for a headbox speed calculation. The use of alphanumeric variables in Reduce is used to choose the corresponding coefficient. Keep in mind that we would like to display m/min.

• Statistic calculations with x or x & y data. If we have two variable, gnuplot package is used to plot and numeric package is used to determine the 2nd order polynomial regression for this data set. I must dig around the Reduce packages to find other statistical calculations; however, keep in mind that there is a STATS package module for the 41CX. Choices, choices!
