My name is Rick. I love HP RPN calculators! Recently, a neighbor who once worked for Hewlett-Packard informed me that she had lots of calculators and that she would give me one. I was so excited. I used to have a HP 41cv. I was hoping that the calculator she would give me may have been a 41cv. But it was a HP 12 c platinum. But still, I was quite excited. I want to write a personal finance cash flow program. I was hoping for the ability to write intrinsic functions and or stack commands ( g gto rcl r# ). Since I discovered that the hp 12 cp does not support these kinds of commands, I performed a conditional branch test to determine what memory register was entered by the user as part of the preliminary stack register input. I performed small kernel programs to test my simple program idea. But when it came to implementing the program into program memory, I discovered that the g gto function did not work. I then went on line to find out what I may do to test the calculator. I then performed a key test which verified that all keys were operable. So I'm thinking that this may be a s/w issue. Am I correct in thinking that there may be a s/w defect and if so is there a way to perform a s/w update? Respectively glad to be a guest at this forum.
