Channels - Command Syntax

The default mode for entering commands in the system is simple to learn, requires few
keystrokes and applies to all functions in the system. It is used a lot in HP calculators for
speedy calculations and is called Reverse Polish Notation (RPN). Since RPN applies to
everything in the system we recommend you spend the necessary 30 minutes to understand
it. There's one single rule: enter the number first and press the function key after.

At Mode (also called (Direct Entry) is different in the way that ch numbers are entered
directly, followed by a function (@ LEVEL for example) and the value of that function.

NOTE
At mode setting is set up and stored in the registry as a system
setting. See

System Settings - General
