I'm about to buy a new hp50G =)

Can we transfer files between the PC and hp50-New RPL?, If so, the binary format will be stable, that is, in the future these files will be compatible.

PS:
An idea: please made the imaginary unit optional
for example XCAS-ti-mode uses as an imaginary unit the character ¡ Inverted exclamation character (Spanish ! -> ¡) there would be no problem for the simulator because that is available I believe in all PC keyboard. the objetive is releasing the vowel i as a counter variable.

The Classpad calculator allows to choose between i, j, and the vowel i is used in electrical and electronic engineering as current
