Full Version: HP 29C strange behaviour

Hello,

While entering a program I made a mistake. I wanted to enter GTO i ([GTO] [ g ] [R arrow down]) but I entered LBL i ( [ g ] [GTO] [ g ] [R arrow down]). As a result, the calc displayed 01 24 22 => RCL 22.
I entered a value in Register 22 (22 STO 0 then 1234567 STO i) and ran the program. It displayed 1234567 !!!
Normally register numbers beyond .5 are not directly accessible. Am I wrong ?

Is this trick known ? Are they some others ?

I tried with other keys but got nothing.
You are misinterpreting your program. The 22 represents the key in row 2 and column 2, which is the indirect addressing function i. So, you are simply performing RCL i, not RCL 22.

This is no trick, it is the normal behavior. You just entered [g] [arrow down] which is RCL i .

The preceding sequence [g] [GTO] is abandoned because the following key replaces it.
