This release also includes a nice little feature suggested by Valentin Albillo to reduce the number of keystrokes when using the INTEGRAL and FNROOT functions.
Now, instead of typing (for instance)
INTEGRAL(0,1,E,IVAR^3-IVAR^2+IVAR+2)
you can just type:
INTEG(0,1,E,IX^3-IX^2+IX+2)

With these additions, the Math Pac 2 reaches the BETA stage, meaning that I will no more add features and will wait for more tests and possible feedbacks before promoting it to the final 2B version.

It's not the end of the Math Pac 2 project, I already have several ideas for future enhancements and it is (very) possible that there will be a version 2C later, but it will not be before several months because I have other projects to complete first.
Also Valentin made several proposals that go well beyond my initial project goals, they may be part of an "Advanced Math Pac" later on.

The Manual Supplement for the Math Pac 2B is available here.

Hello,

quite impressive work ... I will try the new ROM and the features, although with old programs. Today I wanted to install it in exchange of the original ROM in my FRAM71 kit on D0000 so overwrite the old mathrom. I POKEd the IRAM identifier in D0000 but it doesn't run when I tried to copy the LEX file in this port - it ends in an error. Don't want to keep it in memory cause then it is parallel to the old one.
So how can I change it without starting the whole procedure with the FRAM71 again or destroy the actual configuration?
So do you have any idea what I'm doing wrong?

Thanks in advance
Erwin
