Bug with Integers

7^23 MOD 143 ==> 131072

Lower case mod results in syntax error. VC toolbox MOD produces mod. Lots of interesting trivia here.

Clearly Home is for number-crunching(physics, engineering) but in cas-mode the entry mod(7^23, 143) is changed to 7^23 MOD 143 for display, this provides 23 in textbook as well as in algebraic entry mode, manually entered:7^23 MOD 143 provides 2. Interesting and confusing, what does a program using these commands do, well, I have not tested it, MOD/mod is a command that has to work and not to be tested, moreover, everytime I start something on the prime I encounter some unawaited difficulties, here I need to rewrite MOD, some days ago I wanted to make a program providing results for different numerical integrations where I had to use 4 cas-functions, on the 49G+ it was more difficult to get things running, but when I found out how to do, things ALWAYS worked as expected AND like I wanted. How much do I want a 50G using this hardware...
Perhaps I´ll get the emu for my mobile (which is faster than the real device) and go on with the restricted display.
