Hi all,

I am relatively new to the RPL family of calculators, having used the 41C, 15C and 32sii primarily. I recently acquired a pristine 48G for a mere pittance and have been fooling around with the Equation Library. So far, every example that I have worked through from the AUR went flawlessly (with some exceptions like Bernoulli's Equation: Pressure at Depth where Po registers in kPa instead of atmospheres as in the example, consequently giving the wrong answer). The same cannot be said for my 49G+ with the v92 ROM and EqLib L226 and L227 files. On several occasions, certain variables do not have units associated with them and the solver will not work properly. One example would be the 'A' Total Surface Area variable in the Solid Geometry/Cone equations set. This is only an example and has happened elsewhere too. I have purged all variables every time the problem happens and tried reinstalling the library files but to no avail. Has anyone else noticed this or am I missing something fundamental here? Thanks in advance.

Regards,

JeffK
