A way to easily find and purge variables

[yacremann]

Dear all,

I am very impressed by this project! It runs really well on the DM42 hardware and I think it will be a huge step forward for RPN/RPL calculators!

I just have one small suggestion: In the "Solve" menu: Once one has numerically solved an equation / found the root of an equation, the variable X is defined. If I now try to enter a new equation, I can not use the normal RPN entry to define it as X is defined: It will automatically evaluate it and reduce it to a number. The only way I found to avoid this so far was to use the PURGE command. I think it would be great to have an option to purge X directly in the solve menu. In addition, a more powerful purge menu (which can display all the defined variables) would be great. Maybe I am missing something and there is already such a functionality, and I just did not find it.

Again, thanks a lot for this really great project!!

With best regards,
Yves
