RE: HP-65 Top row functions

Every time you switch the HP-65 on, the firmware enters a small program for each of the function keys and matches the alternate functions written above them. You can see the steps in PRGM mode with the SST key.

Code:

LBL

A

g    1/x

4

RTN

LBL

B

f    sqrt

9

RTN

LBL

C

g   Yx

5

RTN

LBL

D

g ROLDN

RTN

LBL

E

g X<>Y

RTN

cheers
