Hi,
I use daily my HP-35S, and despite its bugs, it's a good calculator. I used to use a HP-32SII before, but since I use also some Voyagers, there's a thing that causes me some trouble.
On the HP-32SII, the EQN and the XEQ functions were not on the same level (EQN was behind a shift, I go by heart), so there was not confusion in choosing one or the other.
On the Voyagers, since no EQN is present, you could only distinguish R/S from GSB/GTO, and that was all.
Now, on the new HP-35, the two functions are there, all printed in white, in two different places, but quite every time I have to XEQ a program (GSB on my HP-15C), my eyes - looking for X, E and Q - are captured by E, Q and N and invariably I press EQN instead (hit 2 on 3, and that's not enough!)
You may say that I should wear glasses: I already do it.
You may say I don't program too often: I program quite each day, and I execute a program at least once a day.
The conclusion is simple:
HP: change the XEQ label to GSB. Just to ease this dumb guy's task. ;-)
Ciao!
