Instruction Mnemonics
The table on this page contains an alphabetical listing of the mnemonics displayed for program instructions. For example, the mnemonic #-K represents the pounds-to-kilograms function and is generated by the keystrokes [ CONV ] { MET } { #-K }. The program codes in the table are included for advanced programmers.
